9Mn2V tool steel
Detailed description:
Standard: GB/T 1299-1985
Features and Scope of application:
9Mn2V cold working die steel, 9Mn2V steel is a kind of low alloy tool steel with better comprehensive mechanical properties than carbon tool steel, and it has higher hardness and wear resistance. The quenching deformation is small and the hardenability is good. Because the steel contains a certain amount of vanadium, the grain is refined and the sensitivity of the steel to overheating is reduced. At the same time, the carbide is small and evenly distributed. 9Mn2V steel is suitable for the manufacture of a variety of precision measuring tools, templates, but also for the general requirements of the size of the relatively small die and cold die, engraving die, blanking die, etc., can also do machine tool screw and other structural parts.
