Stellite 6B® High Performance Cobalt Alloy Steel

Alloy 6b® is a cobalt-based steel alloy that provides excellent corrosion resistance in extreme elements and high temperature environments, while also providing outstanding resistance to most types of wear. Stellite 6b® cobalt chromium alloy provides inherent wear resistance that is not the direct result of heat-treatment, plating, nitriding, or other methods used to produce a superficial hardness on metal parts.

Magellan Metals is an industry leading provider of cobalt chrome high-temp alloy for your exclusive project needs. Contact us for more information regarding Stellite 6b® high performance cobalt alloy, or call us at 203-838-5700 and we will happily answer any cobalt chromium alloy questions that you may have.

Stellite 6B® High Performance Cobalt Chrome Material Properties

In addition to Stellite’s outstanding corrosion and wear resistance, tough and durable cobalt chromium alloy steel can be utilized at extreme temperature variables. Stellite 6b® cobalt chrome steel maintains high hardness at elevated temperatures (approaching 2000°F) and will recover its original hardness upon cooling to room temperature. Cobalt chrome also maintains tough erosion and impact resistance qualities.
