Chromium Carbide Overlay Plate Complete FAQ Guide

Chromium carbide is a compound that is widely used in a range of industries. Its most common use is to be integrated into overlay plates, making Chrome carbide overlay plates.

If ever you’re not aware with what they are, this is perfect for you!

In this post, we’ll be discussing everything you need to know about Chromium carbide overlay plates. We’ll start with finding out what it is, what it’s used for, and so on.

Overview of Chromium Carbide Overlay Plates

In a nutshell, Chromium carbide overlay (CCO) plates are plates used in many applications.

You can use it to give higher resistance to wear, abrasion, impact, temperature, and the like.

What is the Hardness of the Chromium Carbide Overlay Plate?

Chromium carbide overlay plate welding layers have extreme-level hardness.

Typically, you can have surface hardness that can reach HRC 58 to 62, and a micro hardness that can go upwards of HV 1700 to 2000.

What is the Flatness of the Chromium Carbide Overlay Plate?

The typical flatness that Chromium carbide overlay plates have must be controlled in the range of ±3 mm per m.

Waldun’s advanced welding processes can strictly control welding deformation, minimizing it to its fullest extent.

Moreover, after welding, we here at Waldun use a welding machine; it’s what we use to level our Chrome carbide plates. In fact, our Chrome carbide overlay plates can reach industry levels even without a leveler.

How Do You Manufacture a Chrome Carbide Overlay Plate?

Waldun follows a 7-step procedure in producing and in manufacturing Chrome carbide overlay plates.

The main advantage that we have is we weld a big plate using a CNC system in one go.

Step 1: Rough Cutting

This procedure involves cutting the raw materials into a plate. This plate will have a rough size, typically in 1500 x 3000 mm.

Step 2: Welding

Then, it will involve open arc welding or submerged arc welding overlay (SAW) on the substrate.

The most common would include one (1) square meter of a Chrome carbide plate; this usually takes four (4) hours (6 + 4, for example).

Step 3: Inspection

Inspection is the part where the quality of the made Chrome carbide plate is checked.

This is when inconsistencies and mishaps are checked and evaluated; if there are, we go to the next step, which is…

Step 4: Repair Welding

All the welding defects you see are fixed in the repair welding procedure.

Whether it’s a crack, overlapping, , porosities, etc., it’s fixed during this phase or process.  

Step 5: Precision Cut

Precision cutting is the process of cutting the CCO plate to the size you need it to be in.

This is where we specify the dimensions of your product or material.

Step 6: Leveling

Based on your desired levelness, we’ll be producing the exact type and kind of Chrome carbide plate.

The normal level is at ± 3 mm per m.

Step 7: Punching and Stud Welding

Last, but definitely not the least is punching and/or stud welding.

This is done in accordance to the actual requirements you have for the design and finalization.

Waldun offers excellent treatment and customization. Don’t be afraid to contact us if you need a particular style or kind of design.
