The new business will cover alloys-based science, cast and machined components, hardfacing materials, and coating services for use in extreme environments involving high temperature, corrosion, and abrasion. The products are suitable for oil and natural gas, power generation, automotive, aerospace/defence, medical/dental, and process and general engineering industries.
Kennametal Stellite now employs approximately 1300 people in seven operating facilities globally, including locations in the US, Canada, Germany, Italy, India and China.
“Deloro Stellite has a long-standing history of providing exceptional value to customers in demanding environments, and we are pleased they have agreed to join the Kennametal team,” said Carlos Cardoso, Kennametal chairman, president and CEO. “The addition of this world-class surface technology and materials science expertise will enhance the range of productivity solutions provided to our customers in extreme wear environments.”
Stellite products include:
- Stellite: Cobalt-based alloys with all-round wear properties. They have wear and heat resistance and are used across a wide range of applications.
- Deloro: Nickel-based alloys which cover a broad range of hardnesses. They tend to have lower melting points which make them well suited for powder welding or spray and fuse.
- Tribaloy: Intermetallic-phase alloys which can be either nickel- or cobalt-based. They perform well in metal-to-metal wear at high temperatures.
- Nistelle: Nickel-based, corrosion-resistant, high-melting-point alloys. They are developed for protection against aggressive chemicals or other corrosive media.
- Stelcar: Nickel- or cobalt-based alloys with carbide particles. They are only available in powder form for coating applications.
- Jet Kote: Carbide and metal combination powders specifically designed for thermal spraying.
- Delcrome: Iron-based alloys designed for abrasive wear resistance at lower temperatures.
- DuraStell: High-performance metal claddings for use in critical applications where corrosion and wear limit part life and reliability. A metallurgical bond is formed with the substrate material, making the process of particular value where conventional alloys and application methods cause excessive part distortion or degradation of high-performance base metals.
Kennametal Stellite also provides rapid product development of cast components, final assembly of power generation steam valves, fully machined parts, and coating services.
