Stellite 6 Powder Nominal composition (mass %) and physical properties as following : Cr :27-32 W: 4-6 C:0.9-1.4 Others : Ni,Fe,Si,Mn ,Mo Hardness :36 – 45 HRC ,380 – 490 HV Density : 8.44 g/cm3 ,0.305 lb/in3 Melting Range: 1285 – 1410°C , 2340 – 2570°F ,STELLITE COBALT BASED ALLOYS, consist of complex carbides in an alloy matrix. They are resistant, to wear, galling, and corrosion and retain these properties at high, temperatures. Their exceptional wear resistance is due mainly, to the unique inherent characteristics of the hard carbide phase, dispersed in a CoCr alloy matrix., STELLITEtm 6 is the most widely used of the wear resistant, cobalt-based alloys and exhibits good all-round performance., It is regarded as the industry standard for general-purpose wear, resistance applications, has excellent resistance to many forms, of mechanical and chemical degradation over a wide temperature, range, and retains a reasonable level of hardness up to 500°C, (930°F). It also has good resistance to impact and cavitation, erosion. Stellitetm 6 is ideally suited to a variety of hardfacing, processes and can be turned with carbide tooling. Examples, include valve seats and gates, pump shafts and bearings, erosion, shields, and rolling couples. It is often used self-mated.
