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.
Stellite 12 could be considered an intermediate alloy between Stellite 6 and Stellite 1. It contains a higher fraction of hard, brittle carbides than Stellite 6, and has increased resistance to low-angle erosion, abrasion, and severe sliding wear whilst retaining reasonable impact and cavitation resistance. Stellite 12 is often used self-mated or running against Stellite 6 or Stellite 1. The higher tungsten content provides better high-temperature properties compared to Stellite 6, and it can be used at temperatures up to about 700 ̊C.
Stellite 12 is typically used for cutting tools that need to withstand abrasion, heat, and corrosion. Examples include industrial knives for cutting carpets, plastics, paper and synthetic fibres; and saw tips in the timber industry. It is also used for control plates in the beverage industry, pump vanes, bearing bushes and narrowneck glass mold plungers; and for hardfacing of engine valves, pinch rollers in the metal-processing industries and rotor blade edges.

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.
Stellite 21 (previously known as Stellite 8) was developed
in the mid-1930s as a corrosion-resistant CoCr alloy, and rapidly found application as a biocompatible hip implant and denture alloy. Many of the alloys currently used in medical applications are variants of the original Stellite 21 composition. It was also one of the first heat-resistant alloys trialed for use in jet engines.
Stellite 21 consists of a CoCrMo alloy matrix containing dispersed hard carbides which strengthen the alloy and increase its hardness but also decrease the ductility. The type, shape, size and distribution of the carbides is strongly influenced
by the processing history of the alloy, and for this reason the mechanical properties of Stellite 21 are very dependent upon the manufacturing route and any subsequent heat treatments.
Due to the low volume fraction of carbides, the Co-based alloy matrix dominates the wear and corrosion properties. Stellite 21 has excellent cavitation, galling, and metal-to-metal sliding wear resistance, but is not recommended for severe hard particle abrasion. The surface can work harden considerably during wear or even during machining, and the use of correct machining tools and techniques is important to achieve optimal results.
Stellite 21 has excellent resistance to thermal and mechanical shock. Optimum high-temperature strength is obtained by solution heat treatments at 1200–1240C (2190–2265F) followed by quenching and aging in the temperature range 700–1150C (1290–2100F).
Stellite 21 can be cast, powder metallurgically processed, or applied as a weld hardfacing. It is recommended for applications involving cavitation, erosion, corrosion and/or high temperatures, such as valve trim for petrochemical and power generation. Due to its good impact resistance, it has been widely used in the building up of forging or hot stamping dies. The oxyacetylene weld deposition method is not recommended for this alloy.

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.
Stellite 1 possesses excellent abrasion and corrosion resistance for applications such as pump sleeves, rotary seal rings, wear pads, expeller screws, and bearing sleeves. It retains its hardness at temperatures in excess of 760°C (1400°F).
Stellite 1 contains a high proportion of hard, wear-resistant primary carbides. These render the alloy well suited to applications involving extreme low-angle erosion and severe abrasion, with some sacrifice in toughness. Compared to other Stellite alloys, it is more crack-sensitive, and care should be taken to minimize the cooling stresses experienced during casting and hardfacing processes. Due to its high hardness and wear resistance, Stellite 1 should only be finished by grinding.

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.
Stellite 12 could be considered an intermediate alloy between Stellite 6 and Stellite 1. It contains a higher fraction of hard, brittle carbides than Stellite 6, and has increased resistance to low-angle erosion, abrasion, and severe sliding wear whilst retaining reasonable impact and cavitation resistance. Stellite 12 is often used self-mated or running against Stellite 6 or Stellite 1. The higher tungsten content provides better high-temperature properties compared to Stellite 6, and it can be used at temperatures up to about 700 ̊C.
Stellite 12 is typically used for cutting tools that need to withstand abrasion, heat, and corrosion. Examples include industrial knives for cutting carpets, plastics, paper and synthetic fibres; and saw tips in the timber industry. It is also used for control plates in the beverage industry, pump vanes, bearing bushes and narrowneck glass mold plungers; and for hardfacing of engine valves, pinch rollers in the metal-processing industries and rotor blade edges.

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.
Stellite 1 possesses excellent abrasion and corrosion resistance for applications such as pump sleeves, rotary seal rings, wear pads, expeller screws, and bearing sleeves. It retains its hardness at temperatures in excess of 760°C (1400°F).
Stellite 1 contains a high proportion of hard, wear-resistant primary carbides. These render the alloy well suited to applications involving extreme low-angle erosion and severe abrasion, with some sacrifice in toughness. Compared to other Stellite alloys, it is more crack-sensitive, and care should be taken to minimize the cooling stresses experienced during casting and hardfacing processes. Due to its high hardness and wear resistance, Stellite 1 should only be finished by grinding.

Key Properties
- Composition: The primary elements are cobalt (base), chromium (26-29%), and molybdenum (4.5-6.0%), with a low carbon content (<0.35%). The lack of tungsten gives it superior resistance to reducing or complex environments (e.g., sulfuric acid) compared to CoCrW alloys like Stellite 6.
- Hardness: It typically has a hardness of 27-40 HRC in its as-cast or as-deposited state. The surface can work-harden significantly, up to approximately 48 HRC (550 HV), during use or machining.
- Wear Resistance: It offers excellent resistance to cavitation, galling (metal-to-metal sliding wear), and thermal and mechanical shock. However, it is not recommended for applications involving severe hard particle abrasion.
- Corrosion Resistance: Stellite 21 is highly resistant to a variety of corrosive media, including seawater and chloride solutions (where it corrodes primarily by pitting) and oxidizing or reducing gaseous atmospheres up to 1150°C (2100°F).
- High-Temperature Strength: It retains its mechanical properties and strength at elevated temperatures, making it suitable for hot applications.
