Industeel CLC 1.2312 Prehardened Mold Steel (300HB/32HRC) with Improved Machinability
Categories: Metal; Ferrous Metal; Carbon Steel; High Carbon Steel; Tool Steel; Mold Steel

Material Notes: Description: CLC 1.2312 is a chromium-manganese-molybdenum grade designed for plastic mold industry. This grade is normally delivered in a prehardened condition at a hardness level of 300HB/32HRC. The grade has a fully homogeneous martensite-bainite microstructure. CLC 1.2312 grade has specific sulfur addition (0.060% typical) in order to increase strongly it's machinability. Compared to CLC 1.2311 grade 30% increase in milling speed and 300% increase in drilling speed can be expected. At constant cutting speed, tool life is multiplied by a least 5 when replacing CLC 1.2311 by CLC1.2312 grade.
