CARPENTER STAINLESS TYPE 420F is a martensitic stainless that is easy to machine, grind and polish. In service it exhibits certain nongalling and nonseizing characteristics. It is used mainly for machined parts that require high hardness and good resistance to corrosion. Its applications include pump shafts, gears, cams and pivots. This alloy is not usually recommended for vessels containing gases or liquid under high pressure. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-400. Producer or source: Carpenter.

HAYNES STELLITE Alloy No. 6B is a cobalt-base alloy that is highly resistant to most types of wear. It has long service life even under constant erosive conditions, and it exhibits high resistance to seizure and galling even without lubricants. Its corrosion resistance is good in a wide variety of media. Its many uses include scrapper blades, screw conveyor flights and sleeves for seawater pump shafts. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as creep. It also includes information on high temperature performance, corrosion and wear resistance as well as heat treating, machining, and joining. Filing Code: Co-23.
