HAYNES Alloy No. 273 is a nickel-base, hard-facing alloy developed to provide extra life for hot-working equipment such as hot-forging dies, hot-shear blades and hot-extrusion dies. It is deposited by using a composite electrode with nickel-base core and the balance of the alloying elements in the flux coating. Deposits retain their hardness up to 1200 F. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Ni-208. Producer or source: Cabot Corporation.

HAYNES STELLITE ALLOY No. 21 is a cobalt-base alloy containing chromium and molybdenum. It is resistant to oxidizing and reducing atmospheres up to 2100 F. It has excellent strength at elevated temperatures that is maintained through aging characteristics occurring in the temperature range of 1300 F to 2100 F. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as creep, deformation, and fatigue. It also includes information on corrosion resistance as well as heat treating, machining, and joining. Filing Code: Co-1. Producer or source: Haynes Stellite Company.
