Abstract Deloro Stellite 21 (UNS R30021), previously known as Stellite 8, is similar to the medical implant alloy ASTM F75. It is a Co-Cr- Mo-Ni alloy that was developed in the mid-1930s as a corrosion resistant alloy, and rapidly found application as a biocompatible hip implant and denture alloy. This alloy consists of a CoCrMo alloy matrix containing dispersed hard carbides that strengthen the alloy and increase its hardness, but that also decrease its ductility. The type, shape, size, and distribution of the carbides are strongly influenced by the processing history of the alloy, and for this reason, the mechanical properties of Deloro Stellite 21 depend greatly on the manufacturing route and any subsequent heat treatments. This datasheet provides information on composition, physical properties, microstructure, hardness, and tensile properties. It also includes information on corrosion resistance as well as machining. Filing Code: Co-139. Producer or source: Deloro Wear Solutions GmbH.

The microstructure and mechanical properties of a new corrosion-resistant alloy GH945 with high strength for oil and gas production were studied in this paper. The results showed that the main precipitations of GH945 alloy after solution heat treatment and two-stage age hardening treatment were γ′ and γ′′ phase, MC-type carbide, σ phase and M23C6-type carbide. The increase of primary aging temperature not only promoted the precipitation of σ phase and film of continuous M23C6 carbide on the grain boundary, but also led to the coarsening of γ′ and γ′′ phase, which resulted in the decrease of yield strength and impact toughness. Alloy with high Nb content had high strength but low impact toughness. The following heat treatment was preferably used to obtain the combination of high strength and excellent ductility and toughness for GH945 alloy: 1010 °C/70 min, WQ+ 735 °C/9 h + FC to 615 °C/18 h, AC.
