As a matter of fact, you can find many different kinds and variations of CCO wear plates in terms of pattern, type, procedure made, and the like.

In this buying guide, we will help you find the best CCO wear plates in the market. We’ll dissect everything from the chromium carbide wear plate manufacturer, the type of material used – to the finishing procedure.

How CCO Wear Plates are Made

In the simplest and the easiest terms, here’s a quick peek of how chromium carbide wear plates are manufactured:

Plasma Cutting
Plasma cutting is done to produce the required shape/dimensions of the wear plate

  1. The steel plates are sourced out and are run through rotating tubes. They’re bended for them to drum.
  2. If the client requires a large-sized CCO wear plate, then smaller steel plates would be welded together to make up a large part.
  3. Then, using welding, the plate is cladded by the material – in this case, chromium carbide at the surface.
  4. Depending on the size of the steel plate would be the number of the welding heads running simultaneously.
  5. After cladding, plasma cutting and other cutting procedures are done to produce required shapes and dimensions of the CCO wear plates.
  6. Then, depending on the manufacturer, the final product is heat treated to a temperature it can resist. This treatment is done to harden the wear plate further.

That’s the general procedure on how a CCO wear plate is produced and manufactured. Other manufacturers might have other methods and processes; that’ll depend on the manufacturer already.

Purpose of CCO Wear Plates

Chromium carbide overlay wear plates are used by a lot of industries because of the promising results they’re guaranteeing.

Wear Plate Installed

As a matter of fact, CCO wear plates are perfect for situations and environments that have high abrasion, high corrosion, and high friction.

You can use CCO wear plates for:

  • Prolonging the life or the effectiveness of machines and equipment
  • Restoring or rehabilitating the dimensions and the shape of parts and components
  • Decreasing and overall removing the risk of the parts wearing out
  • Controlling the abrasion-level of each of the machine or the equipment’s part or component
  • Helping the overall effectiveness and efficiency of the part/component

Those are the main and primary purposes of chromium carbide overlay wear plates. All of these are applicable to many different industries and sectors; it’ll just depend which one you are in.

Having More Layers – Are They Better?

When dealing with CCO wear plates, the wide majority of people think that the more layers a particular wear plate has, the better.

Since their main purpose is to absorb friction and abrasion, not letting it reach the part itself, you’d think the same, right?

However, that is not true. Having more does not always translate to good or better.

Even if there’s just one pass or one layer of chromium carbide wear plate, if it has been welded properly and appropriately, and if the chemistry of the elements and compounds are compatible with one another, it’ll be better than a normal and a regular CCO wear plate that has a double pass.

Industries That Use CCO Wear Plates

Many industries and business areas feel the need to use chromium carbide overlay wear plates.

The Pulp And Paper Industry
The Pulp and Paper industry – one of the industries that use CCO wear plates

The most common industries that are vocal about their need to use CCO wear plates include the construction or the structural industry, and the heavy earth moving industry.

To cite other industries that need it, they are:

Gas and Oil Industry

The gas & oil industry use wear plates for many different parts and components, including valves, boilers, heat exchangers, compressors, chutes, conveyors, and many more.

Pulp and Paper Industry

For the pulp and paper industry, wear plates are regularly applied and integrated to refiners, pulpers, chippers, cyclone fans, mixing machines, pipelines, etc.

Mining or Coal Mining Industry

With the mining and/or coal mining industry exposed to frequent abrasion and friction, the use of wear plates has been seen as a standard in many different situations.

As a matter of fact, the most common machines/equipment that are installed CCO wear plates on include dumpers, bulldozers, graders, excavators, rotary blades, loaders, and many more!

Apart from those industries, there are other industries that rely on chromium carbide overlay wear plates for the life and the prolonging of their parts/machines.

Does Paint on Wear Plate Really Matter?

The quick and easy answer to that is no – wear plates, especially chromium carbide overlay plates wouldn’t have too much of a difference if it has solid paint or not – or if the paint is cranked and mixed up.

This probably is the most common misconception that experienced and seasoned workers have when choosing CCO wear plates.

Color shall never be a side of judgment in choosing which CCO plates to buy. As a matter of fact, you might even see hairline cracks, check-cracks, and other thin lines on the CCO plate when you first purchase it.

To be fair, they’re completely normal! Seeing a thin-line crack isn’t a sign that the CCO plate has been damaged or worn-out; it is, in fact, a natural stress relieving effect that the plates have.

How to Choose the Chromium Carbide Overlay (CCO) Wear Plate to Buy

There are a couple of things you should look for before you purchase chromium carbide overlay wear plate.

As mentioned above, the thickness or the number of passes isn’t significant enough if the chemistry is not thought of fully.

That being said, here are the best tips so you’ll be able to purchase the best and the highest quality of CCO wear plates.

Bigger Plates are Always Better

While pass thickness isn’t much of a big deal, the larger the size of the CCO plate, the better.

Imagine a wear plate that’s smaller than the bucket you’re trying to cover. Also, if you are going to install it on a loader or an excavator, would a small one fit it? Probably not!

There are manufacturers that produce large-sizes chromium carbide overlay wear plates, while those that just weld two (2) or more small pieces together. You need to make sure that you’re purchasing large and wide-sized CCO wear plates for better results.

So, checking on the history, the background, and the overall capability of the manufacturer is important. We’ll get to that in a later part of this guide.

Ask For Samples

Most, if not all CCO wear plate manufacturers offer free samples to clients and businesses. These samples are ways to check if the product or the CCO wear plate is fit to the need of the client.

Should they provide a sample, you can do and perform tests and assessments to that particular sample.

But, there are a few chromium carbide wear plate suppliers that do not offer samples; it’ll be better to work with a manufacturer that provides free samples.

The Hardness Level Isn’t Always Important

Different chromium carbide overlay wear plates have different hardness levels. The hardness would depend on a wide range of factors, such as the heat treatment, the material used, and many more.

On average, the hardness levels of chromium carbide overlay or CCO wear plates are usually around 59 to 64 HRC.

But, the harder the wear plate is, the more brittle and fragile they are. High-level hardness CCO wear plates are prone to cracking, breaking, and splitting.

How is Hardness Measured?

To add extra information and knowledge to this, here’s how hardness is measured.

Measuring the hardness of a particular item can be done in many different ways. However, the most common ones are the Brinell and the Rockwell scale.

Typically, measuring the hardness of CCO wear plates is done via the Rockwell (HRC) or the Hardness Rockwell C.

59 HRC, when converted to Brinell, is 590 HB. 64 HRC, on the other hand, is measured ad 668 HB.

The higher the number, the harder the particular item or CCO wear plate is. So, it might seem typical to see the regular or the average hardness level of chromium carbide overlay wear plate is at 59 to 64 HRC.

However, different manufacturers, use different materials and products to produce and to manufacture CCO wear plates – they’re not all the same.

There are manufacturers that produce malleable CCO wear plates, while there are those that manufacture CCO wear plates that have HRC levels over 72.

Other Factors You Need to Consider

In choosing the CCO wear plate, you don’t just have to focus on the hardness. There are other properties you can choose from as well.

Hardness Wear Plate
Apart from hardness, you also need to consider other factors and properties

Service Temperature

This property measures the capacity of the CCO wear plate to be worked on under temperatures.

If we put it in average, the maximum service temperature of these plates is at 600 to 650 degrees Celsius or 1,100 to 1,200.


When it comes to the impact, this is the capability of a CCO wear plate to be able to resist and absorb impact.


The amount of abrasion resistance of a particular chromium carbide overlay plate depends on the composition of it.

Abrasion refers to the wearing out of the surface such as scratching, rubbing, and marring.

Service Life/Life Expectancy

Lastly, the service life or the lifespan of the CCO wear plate is relevant and significant as well.

Although the life expectancy would still depend on usage, as well as other external influences, manufacturers give the expected service life of their CCO wear plates for clients to have a general threshold of until when they’re effective.

Look Into the Manufacturer/Supplier’s Capability

While these things are a lot to digest, the best thing to do is to still look into the legitimacy and the experience of the manufacturer you’ll be working with.

The quality and the overall effectiveness of chromium carbide wear plates will, of course, depend on the one who made it.

If the chromium carbide wear plate manufacturer isn’t reputable or if they’re known to provide CCO wear plates that are not-up-to-standard, then you should already think twice about working with them.  

To illustrate further, there are newer manufacturers of wear plates that skip heat treatment because they think it’s not a collaborative factor in the strength and quality of the material. These manufacturers are obviously inexperienced and are not used to other procedures in which wear plates are used for.

To successfully check the background or the history of a manufacturer, you can try the following:

Check Reviews

While the reviews you see online aren’t much impacting, the reviews that real clients they had could be everything you need to decide.

If you see a line of reviews that is 100% positive – then, the chances of that manufacturer being world-class is higher, you can immediately come up with a conclusion that they’re easy-to-work-with.

Speak to Previous Clients

Another thing you can do is to find previous clients of that particular manufacturer. Try communicating with those clients and ask about the service and the products the manufacturer is offering.

Were they up to the expectations of the client? Or were there a lot of challenges towards completion?

Check Their Manufacturing Plant/Office

Lastly, the condition or the ambience of the manufacturing plant reflects directly on the quality of service the manufacturer has.

Since the rise of technology, many suppliers opened a virtual setting of their manufacturing plants and offices.

This paved way for clients to be able to “visit” their factories without being physically there. Oftentimes, the best manufacturers would offer a virtual tour of their factory.

They wouldn’t be shy to let their factories and their manufacturing processes out.

Which Manufacturer Should You Trust?

It has been a long debate in terms of which manufacturer you should work with. Some businesses and companies say that choosing a Western manufacturer is better (those in Europe and in North America), while some say that you’ll be able to get the best products in China.

The latter, probably, is the closest because of a lot of different factors:

  • Cheap, inexpensive, and affordable goods
  • High quality of products (ODM and OEM)
  • Many variants and variations of the orders and the products you need
  • A lot of manufacturers to choose from (tight competition, better quality)
  • And many more
