Stellite 21 AM Powder for Laser Powder Bed

The first Stellite powder qualified for laser powder bed additive manufacturing, Stellite 21 AM powder features the unique corrosion and wear-resistant properties of the Stellite alloy family for laser powder bed additive platforms to produce high-performance wear components for the oil & gas and power generation industries. The powder’s composition features a Cobalt Chrome-Molybdenum alloy matrix, containing dispersed hard carbides which strengthen the alloy and increase its hardness while decreasing the material’s ductility. It also has excellent corrosion and thermal shock and mechanical shock resistance.

It is suited for flow control applications and can be integrated into complex designs to mitigate cavitation, erosion, or corrosion failures. Stellite 21 AM is available direct to customers for use in their own 3D printing applications or in combination with Kennametal’s end-to-end additive production capabilities to make fully finished components.
