Plastic mold steel for medium and large molds. As this material is pre-hardened to 950-1,100 MPa in its delivery condition, it is also suitable for parts in general mechanical engineering. In comparison to 1.2311, 1.2312 is more easily machinable due to its sulfur content, but not suitable for polishing. Both materials can be gas and ion-nitrided, making them suitable for case hardening.
You can obtain 1.2312 from us as precision flat steel in special dimensions, as VarioRond, and as raw material cuttings.
You can also obtain 1.2312 from us individually, according to your specifications, as a finished machined drawing part.
