Hardsurfacing provides protection against abrasion, corrosion, impact, heat friction and other wear. In the selection of the proper type of hardsurfacing material, the question should not be 'which is the hardest build-up alloy?' but which allow wears the longest under the specific conditions?
Experience shows that the relative abrasion resistance of hardsurfacing alloys is due to the amount of metal carbides present in the alloy. The more carbides, the greater the resistance to wear.These carbides are natural chemical components, formed by the union of one or more of about a dozen elements, among which are Tungsten, Chromium, Molybdenum etc...................
