Stellite 6K – Cutting and Scraping Solutions for Severe Environments
Kennametal’s Stellite 6K is a hot-rolled material designed for industrial cutting and scraping applications. The carbon content of Stellite 6K is higher than Stellite 6B allowing for a higher hardness and better edge retention.
Stellite 6K is designed to hold a sharp edge in high-temperature, corrosive, and severe service environments. Stellite 6K knives, scrapers and slitters are found in a wide range of production equipment where edge-holding, quality of cut and resistance to corrosion are critical.
Stellite 6K is available in thicknesses ranging from 0.045" to 0.375“ and can be custom-rolled to your specification. Additionally, Kennametal Stellite can fabricate and finish Stellite 6K to print.

Stellite 6K in Industrial Processing Equipment
Stellite 6K is used in high-volume production equipment where long-life precision cutting & scraping is required. It is often operating in corrosive conditions or with harsh processing chemicals. Stellite 6K also offers the toughness required to reliably withstand the processing environment – all while maintaining a precise edge.
Stellite 6K is used in industrial filtration, food processing, viscose fiber and textile processing, packaging equipment and in many other critical applications.
