New Kennametal unit focuses on wear solutions

With the acquisition of U.K.-based Deloro Stellite, Kennametal’s newest business unit, Kennametal Stellite, provides wear-resistant solutions in alloys-based science, cast and machined components, hardfacing materials, and coating services for wear-resistance in extreme temperatures and applications.

A global manufacturer and provider of alloy-based critical-wear solutions for extreme environments involving high temperature, corrosion and abrasion, Kennametal Stellite employs approximately 1,300 people across seven primary operating facilities globally, including locations in the U.S., Canada, Germany, Italy, India and China. It combines proprietary metal alloys and materials expertise with specialized engineering design and fabrication capabilities to deliver value-added, tailored wear solutions for customers in oil and natural gas, power generation, automotive, aerospace/defense, medical/dental, and process and general engineering segments.

“Deloro Stellite has a longstanding history of providing exceptional value to customers in demanding environments and we are pleased they have agreed to join the Kennametal team,” commented Carlos Cardoso, Chairman, President and CEO of Kennametal Inc., Latrobe, Pa. “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 the best ‘all-round’ wear properties. They combine exceptional wear and heat resistance and are used across a wide range of applications.
  • -Deloro: Nickel-based alloys which cover a broad range of hardness'. They tend to have lower melting points which make well suited for powder welding or spray and fuse.
  • -Tribaloy: Intermetallic-phase alloys which can be either nickel- or cobalt-based. They perform exceptionally well in metal-to-metal wear at high temperatures.
  • -Nistelle: Nickel-based, corrosion-resistant, high-melting-point alloys. Developed for protection against aggressive chemicals or other corrosive media.
  • -Stelcar: Nickel or cobalt-based alloys with carbide particles. 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 value-added services as rapid product development of cast components, final assembly of power generation steam valves, fully machined parts, and coating services. Parts are produced through different processes such as investment casting and finish machining, and are custom-engineered to meet individual customer needs. In addition, Kennametal Stellite offers its expertise and experience in coating services in the form of HVOF (High-Velocity Oxy Fuel) coatings and weld hardfacings.

Kennametal Stellite provides critical-wear solutions including coatings, hardfacings, castings and even component development, such as these used in glass container manufacturing.
