What is Stellite 6K?
Stellite 6K is a cobalt alloy that has been used by other makers like David Boye, Mick Strider, and Tom Mayo. Like tungsten carbide, Stellite 6K is extremely resistant to rust. But, Stellite 6K isn’t as temperamental and can be worked with standard knife making equipment instead of costly custom machinery.
Can you sharpen Stellite?
by Bruce Creps. With a shop-made jig you can sharpen your blade in place in less time than it takes to remove and reinstall it. I once used an alternate-tooth Stellite blade and got better performance when I increased its cutting angle from 16° to 22°.
Is Stellite a metal?
Stellite® is a non-magnetic alloy which contains a variety of different metal components with the main elements being cobalt and chromium.
Who made Stellite?
Elwood Haynes
The Stellite range of alloys were first developed by Elwood Haynes in the early 1900s as an alternative for cutlery that was susceptible to staining. Stellite is a trademarked name of the Deloro Stellite Company, now part of the Kennametal group.
What is Stellite used for?
Stellite Uses Stellite alloys are used in the process of hardfacing. They are also applied in the manufacturing of saw teeth and acid-resistant machine parts. The invention of Stellite alloys greatly improvised the manufacturing of poppet valves as well as the valve seats for valves.
How do you weld Stellite?
They are usually welded using a low preheat temperature (50-150°C) followed by a slow cool in vermiculite. The difficulty with austenitic steels is that during hard facing, carbon can diffuse from the Stellite alloy into the heat affected zone (HAZ).
Is Stellite brittle?
Stellite 6B offers both. An extensive hot forging process transforms brittle ingot into the tough, wear-resistant Stellite 6B. Don’t let the hardness range of 33-43RC fool you, the surface of this material goes through an extensive transformation that provides unmatched wear resistance for such a tough material.
Can you weld Stellite?
Stellite welding provides excellent resistance to corrosion. This is due to the inherent characteristics of the hard carbide phase dispersed in an alloy matrix which allows Stellite coatings even at high temperatures to retain their corrosion resistance properties.
What is Stellite welding rod used for?
Stellite is basically a cobalt alloy that is mainly used in wear applications, fusion welding, a spraying process, and hard facing applications.
How is Stellite applied?
Kennametal Stellite uses various thermal spraying techniques to apply wear-resistant coatings to components, including High Velocity Oxygen Fuel (“HVOF”) spraying, plasma spraying, and flame spraying.
What is hard welding?
From Wikipedia, the free encyclopedia. Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and gas tungsten arc welding welding.
What is Stellite welding?
Stellite is basically a cobalt alloy that is mainly used in wear applications, fusion welding, a spraying process, and hard facing applications. This alloy has an excellent combination of wear resistance, corrosion resistance, high strength, and all these features make them adaptable to the harsh environment.
How does Kennametal Stellite make a knife edge?
The key is the extensive hot forging process the material goes through which results in a Stellite sheet material which can be honed to create a fine knife edge. Kennametal Stellite™ offers both off the shelf and custom solutions for HVOF and PTA coating applications.
How is Stellite 6K used in industrial applications?
Thanks to Stellite 6K, applications such as industrial knives and scrapers remain sharp 4x longer than other hardened D2 materials. This specialty formulated material is designed for outstanding performance in the harshest cutting and scraping applications.
What makes a Deloro Stellite knife edge so good?
This specialty formulated material is designed for outstanding performance in the harshest cutting and scraping applications. The key is the extensive hot forging process the material goes through which results in a Stellite sheet material which can be honed to create a fine knife edge.
What’s the standard heat treatment for Stellite 6b?
Wrought forms of Stellite™ 6B and Stellite™ 6K are supplied in the solution heat-treated condition, unless otherwise specified. The standard heat treatment is at 2250°F (1232°C) followed by air cooling.
