1. Steel Grade: DIN1.2312 GB3Cr2Mo
2. Product name: DIN1.2312 GB3Cr2Mo Hot worked Mould Steel Pipe
3. Length: 20m maximum
4. Outside diameter: 3mm - 219mm
5. Wall thickness: 0.5 - 35mmDescription 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.
