ST12 wear-resistant steel powder
ST12 wear-resistant steel powder
ST12 (Stellite) is a cobalt-based superalloy, characterized by high hardness, excellent wear resistance, and corrosion resistance. These properties are typically achieved through the dispersion of a large number of hard carbide phases (such as Cr7C3) within the cobalt-based solid solution, offering a "good balance of hardness and toughness." It is especially suitable for high-end additive manufacturing and surface engineering applications.
