1.2311 steel hardness is HRC28-35 (i.e. pre-hardening), which can be directly used after cold working. In this way, the service performance of the die is guaranteed and the deformation of the die caused by heat treatment is avoided. Therefore, this kind of steel is suitable for large manufacture. Medium and precision plastic moulds and die casting moulds for low melting point tin,zinc and lead alloys. 1.2311 steel differs from area to area.Europeans generally use the DIN spec-DIN EN ISO 4957 standard materials (1.2311 and 1.2312), while in Japan steel industry standard, PX5 is the new standard 1.2311. And in American,P20 is the most and wide used steel grade material. In China, 3Cr2Mo is the 1.2311 steel grade equivalent, which is in the standard GB/T 1299 tool steel specification.
