Check cracking occurs as a natural phenomenon during welding and is controlled by the chemical composition of the overlay or by cooling methods. Overlay deposit chemistry ranges from 15% to 30% Chromium, 3.0% to 4.5% Carbon. Manganese, and Silicon may vary from 1% to 4% each. Molybdenum may exist up to 3%.
China Chromium Carbide Wear Plate Manufacturers and WD1200/WD1500 wear plate is suitable for application involving severe abrasion and low to medium impact. WD1200/WD1500 series:High chromium high carbon wear plates produced by submerged arc welding; Suited for applications involving severe abrasion and low to med
Recommended for resistance to wear by abrasion, fretting, cavitation, and particle erosion in high temperature applications (up to 1100°F). Ideal for mild to moderate impact abrasion resistance. Low maintenance cost and easy installation. The overlay surface of CCO plate will consist of a series of beads with numerous hairline cracks in them.
High chromium high carbide overlay abrasion wear resistant Wear plates manufactured by welding one or multiple wear resistant layers on a medium or low carbon steel base plate. The overlay alloy has a high amount of chromium carbide hard particles which makes the plate have good wear and impact resistance. Overlay thickness range:3-25mm. Wear plate size:1400*3000,1400*3400, 1400*3500, 2100*3500
Kalenborn Abresist KALMETALL® Overlay Plates with KALMETALL® chrome carbide weld overlay, standard grades of carbon and AR plate into wear resistant plates, piping and a variety of complete wear protected structures and assemblies. KALMETALL can also be adapted to specific uses by varying the alloy of the hard overlay welding. KALMETALL incorporates several hard overlay welded
The recommended method of cutting overlay plate is by plasma-arc, as the high chromium and carbon contents of the hardfacing overlay preclude the use of oxy-fuel and most mechanical means. The special properties of the very hard overlay alloy and a ductile substrate allows these materials to be formed and fabricated into complex shapes, including concave or convex curves.
The Use of Protective Weld Overlays in Oil Sands MiningThe compositions of chromium carbide-based hardfacing alloys are essentially based on high chromium cast irons. Typically, the grades of alloy will contain in the range of 25 to 32 w% chromium and up to 5% of carbon. Their microstructures tend to contain large amounts of M 7 C 3 carbides, where M can represent metals such as chromium, iron or
