DESCRJPTION / APPLICATION
Oxford Alloy #21 Coated is a low carbon, molybdenum strengthened, cobalt-chromium alloy. This electrode is recommended for metal-to-metal abrasion and high impact applications involving high temperatures and/or corrosive media. Some typical applications are valves of all kinds, shear blades, hot punches and saw guides. Oxford Alloy #21 Coated is also used as hot die material because of its high temperature strength and stability. Its inherent resistance to galling (under self-mated conditions), cavitation erosion, and corrosion resistance have made it a popular fluid valve seat-facing alloy. The weld deposits of the Oxford Alloy #21 Coated are smooth and normally acquire mirror-like finish in use. The deposits retain wear resistance at high temperatures. This alloy is nonmagnetic and is not forgeable. It can be machined with carbide tools. Oxford Alloy#21 Coated bonds well with weldable alloy steels, including stainless.
