Stellite™ Blog

When it comes to materials that excel in extreme environments, Stellite™ alloys stand out among some of the most reliable and durable options available. Kennametal Stellite provides reliable, proven, precision-engineered wear protection material solutions that people have trusted for more than 100 years. In this blog, we'll explore the key aspects of Stellite alloys, how they differ from other materials and why they are so effective in challenging environments.

In the aerospace industry, the demands placed on materials are incredibly high as components must withstand extreme temperatures, mechanical wear, and corrosive environments while maintaining structural integrity. Over the years, certain alloys have proven to be exceptional in meeting these rigorous standards. Among them, the Kennametal Stellite™ family of alloys stands out as a key player in ensuring the longevity and performance of aerospace components. Stellite™ alloys have played a historic role in aerospace, with some of these materials dating back to the early 1900s. Today, they continue to push the boundaries of aerospace.

Refineries using Fluid Catalytic Cracking (FCC) processes face extreme operational conditions that test the durability of their equipment. One critical component in this process is the catalyst withdrawal spool, which transports and recycles catalyst particles and gases. These conveyance spools must withstand high temperatures, abrasive materials, and high-velocity flows, making them vulnerable to wear and erosion. 

In modern power generation and petrochemical processes, energy recovery systems play a crucial role in maximizing efficiency and reducing operational costs. Among these systems, hot gas expanders are integral components, particularly in processes like fluid catalytic cracking (FCC) and gas turbines. Their role in converting thermal energy into mechanical energy has a direct impact on performance, longevity, and cost-effectiveness. Explore the importance of hot gas expanders and how Kennametal Stellite™ leverages advanced alloys to improve durability and reduce downtime.

In fracking, frac plungers are essential components that endure harsh abrasive and corrosive environments. These plungers are subject to intense wear due to friction, high-pressure fluids, and exposure to chemicals. To extend their operational life and reduce maintenance costs, advanced coatings are needed. Kennametal Stellite’s Deloro 60 Alloy offers an effective solution to enhance the durability and longevity of frac plungers.

Explore Kennametal Stellite’s unique solution to extending the life of steam turbine blades suffering from water droplet erosion. Learn how erosion shields can help extend the life of turbine blades.

In the aerospace industry, where performance and reliability are paramount, materials must withstand some of the harshest environments imaginable. A standout material solution to these challenges is Kennametal Stellite’s family of Tribaloy alloys.

For more than 70 years, the Stellite family of alloys & products has been relied on by the timber & wood cutting industry for some of the most aggressive cutting environments. Saw tips made from Stellite provide saw mill operators with a variety of benefits like longer working periods between resharpening, improved dimensional accuracy & product quality, strong bonding to the steel blade, easy tip repair & re-sharpening, elimination of tip hardening or heat-treatment, and excellent corrosion resistance across a variety of timber species.
