AMDRY 850 is a cobalt-base alloy formulated to provide maximum resistance to combinations of abrasion, corrosion, heat and oxidation. It has superior resistance to certain corrosive media and higher hot hardness than nickel-base alloys. Produced in powder form, it allows large areas and cylindrical shaped parts to be hardfaced by spraying and fusing, which is faster and more economical than alternative methods. Sprayed deposits are usually limited to a thickness of 0.080-inch. The data pertain to the deposit after fusing. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and machining. Filing Code: Co-70. Producer or source: Alloy Metals Inc..
