Stellite 21

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.

• Highest Hardness: It possesses the highest hardness among the standard cobalt alloys (typically 50-55 HRC), which it retains well at high temperatures (up to 800°C or more).
• Excellent Wear Resistance: The high carbon and tungsten content results in a large volume of hard primary carbides in the microstructure, making it highly resistant to solid particle erosion and metal-to-metal wear (galling).
• Corrosion and Oxidation Resistance: High chromium content provides good resistance to oxidation and corrosion in harsh chemical and marine environments.
• Low Toughness: Due to its high hardness and high carbide content, the Co1 deposit is less tough and more crack-sensitive compared to other cobalt grades (like Co6 or Co12), meaning careful preheating and controlled cooling are crucial during welding.

Cobalt-based alloy welding electrodes are primarily used for hardfacing and cladding applications that require exceptional resistance to wear, heat, corrosion, and galling in severe operating conditions. They maintain their properties, including high hardness, at elevated temperatures where many other alloys would fail. Key Properties

• High Temperature Strength: Cobalt alloys retain significant strength and hardness at temperatures up to 800-1000°C (1470-1830°F).
• Wear Resistance: They offer excellent resistance to various types of wear, including abrasive wear, metal-to-metal wear, impact, and cavitation erosion.
• Corrosion and Oxidation Resistance: The high chromium content (typically 25-35%) provides superior resistance to chemical degradation and oxidation, even in harsh or marine environments.
• Galling Resistance: They possess outstanding self-mated anti-galling properties, meaning they resist seizing when in contact with other metal surfaces.
• Thermal Stability: These alloys exhibit high resistance to thermal shock and fatigue.

A Co1 cobalt-based welding electrode, also known by the trade name Stellite 1, is a high-performance hardfacing electrode designed for applications requiring exceptional resistance to wear, corrosion, and high temperatures. Its unique properties come from a high proportion of hard, wear-resistant chromium carbides within a cobalt-chromium-tungsten alloy matrix. Key characteristicsCo1 electrodes offer high hardness that is retained at temperatures up to 900°C (1,652°F), making them suitable for severe abrasion and low-angle erosion applications. They also provide excellent resistance to corrosion and oxidation. However, due to high hardness, Co1 is susceptible to cracking, requiring careful welding techniques, and has unsatisfactory impact resistance. The extreme hardness necessitates grinding for finishing.
