What types of material are chromium carbide cored welding wires made of?

  • Alloy Chemistry

    The highest ordinary used alloy facing is a high chromium iron consists of precisely 1/3 of Chromium and in surplus of 4% combined carbon.

    WALDUN is making this to correlate to CCO plate with the chemistry of Chromium of 34.0%, carbon of 5.4%, Manganese of 3.5%, and the others at 1.3%, Balance Fe.

    Meanwhile, this standard alloy can be changed in many different ways; it can improve the abrasion resistance while lowering the toughness, or the other way round. On the contrary, the matrix can be made harder by reducing the manganese to 1%, with some reduction in firmness. Also, further refinement may be accomplished by the addition of other alloying elements.

  • Carbides

    The substance that provides high chromium powder alloys with their capability to withstand abrasion is the establishment of primary carbides from a chemical compound of iron, Chromium, and carbon, or iron, Chromium, or carbide, which is also known as chromium carbide. Pure, high rate chromium carbide can be manufactured; however, it is costly for large-area preservation, so WALDUN makes use of mixed carbide, which involves both Chromium and iron. This makes up the primary carbide with the formula M7C3, where M specifies the mixture of metal and Chromium in the compound.

  • Hardness

    A standard overlay alloy consists of a compound of chromium carbides in a matrix of a chromium iron-carbon alloy. The hardness of primary chromium carbides is proportionate of 1700HV correlate with. For instance, ordinary workshop steel files, with firmness of 600HV. In general, the hardness of these alloys can be calculated using a Rockwell hardness tester. Even though it neither measures the carbide or the matrix, it gives an agreeable general proof of the hardness of the alloy. An average value of being 54-60 HRC.

  • Microstructure

    In the extension of chemistry, the most significant characteristic of the alloy overlay is its microstructure. Hence, when checked out under a microscope, the carbides will take the form of white substance against a dark background, that that’s the matrix. A perfect microstructure, for more excellent abrasion resistance, must have a dense array of needle-like carbides that, in cross-segment, look as slender hexagons with a small hole in the middle.

    Moreover, whenever you notice an appearance of uneven shaped spots or avenues of white. Such as either ladder, fish-bone patterns, or central poles with rungs on any of the sides. This is a sure sign that the carbon content is beneath optimum for high abrasion resistance, but it has also improved impact-resistant properties.

What types of companies are buying chromium carbide welding wire?

Any company that has equipment for producing chromium carbide or tungsten carbide wear plates.

Are there different types of chromium carbide welding wire?

Yes, we have different types of welding wires. Below table is clear:

  6. The packing is strictly in line with the customs requirements.

What else should I know before I order my chromium carbide welding wire?

You should know the what hardness of the plate is and what the intent is of the liner. The harder the plate that is used, the longer it will last in service, but there are trade-offs. For some parts, you will need a softer material that is intended to wear out before your primary surface.
