9Cr18MoV Steel

9Cr18MoV stainless steel is a high carbon martensitic stainless steel, and mainly used to manufacture parts that resist strong friction and work in corrosive media, such as stainless steel blades, mechanical cutting tools, surgical blades, measuring tools, and other high-wear parts.

The performance and use of 9Cr18MoV steel (90Cr18MoV) is similar to 9Cr18. Due to the addition of molybdenum (Mo) and vanadium (V), the thermal strength and tempering resistance are better than 9Cr18 steel.

9Cr18MoV (old name) = 90Cr18MoV (new name)
