Description
A prehardened mold steel (300 HB/32 HRC) with improved machinability
W1.2312 is a chromium - manganese - molybdenum grade designed for plastic mold industry. This grade is normaly delivered in a prehardened condition at a hardness level of 300HB/32HRC. The grade has a fully homogeneous martensite - bainite microstructure. W1.2312 grade has specific sulfur addition (0.060% typical) in order to increase strongly its machinability. Compared to W1.2311 grade, 30% increase in milling speed and 300% increase in drilling speed can be expected. At constant cutting speed, tool life is multiplied a least by 5 when replacing W1.2311 by W1.2312 grade. W1.2312 is not suitable for polishing requirements.
