X210CrMoV12

X210CrMoV12 is a high-alloy tool steel known for its excellent wear resistance and high hardenability. It is a cold-work tool steel that contains significant amounts of chromium, molybdenum, and vanadium. The chromium content, typically around 12%, contributes to its stainless properties and corrosion resistance, while the molybdenum and vanadium enhance hardness and wear resistance, particularly at elevated temperatures.

This steel is widely used in applications requiring high durability and resistance to abrasion. Common uses include the manufacturing of cutting tools, stamping dies, cold extrusion tools, and shear blades. Its ability to maintain hardness after heat treatment, even at relatively high temperatures, makes it suitable for demanding metalworking operations. The precise heat treatment process is critical for achieving the desired properties, typically involving hardening and tempering. The microstructure of X210CrMoV12 after proper heat treatment consists of fine, uniformly distributed carbides within a martensitic matrix. These carbides are responsible for its superior wear resistance. It is important to note that while it offers some corrosion resistance due to its chromium content, it is not a fully stainless steel and may require protective coatings or careful handling in corrosive environments.
