Description
1.2358 / X60CrMoV18-5 Cold Work Tool Steel
Chrome-molybdenum-vanadium steel is characterized by high toughness and good resistance to the wear. Further the steel has good hardenability and good dimensional stability after hardening and tempering. The steel can also be well welded and well polished. The toughness of quality 1.2358 reaches higher values than by other steels for cold work (1.2842, 1.2363, 1.2080, 1.2379, 1.2436). An excellent combination of toughness and resistance to the wear enables the usage of quality 1.2358 also for different pressing and injection applications during plastics processing.
Applications
For cold work and for molds for plastics. In case of using for cold work we can talk mainly about these applications: cutting and mechanical working (also materials of bigger thicknesses), deep drawing, punching, rolling, production of shear blades, more complicated tools for cold work. In the area of molds for plastics the steel can be used e.g. for molds for large series, molds for plastics with additives, tools for plastics stamping etc.

Suitability
Steel W. Nr. 1.2358 can be used both for cold work and for molds for plastics. In case of using for cold work we can talk mainly about these applications: cutting and mechanical working (also materials of bigger thicknesses), deep drawing, punching, rolling, production of shear blades, more complicated tools for cold work. In the area of molds for plastics the steel can be used e.g. for molds for large series, molds for plastics with additives, tools for plastics stamping etc.
