1.2379 COLD WORK TOOL STEEL

1.2379 is a kind of mold steel with high compressive strength, high surface hardness,great durability after hardening, good though-hardening properties and high wear resistance. These characteristics combine to give a steel suitable for the manufacture of medium run tooling for applications where abrasive wear is dominant and the risk of chipping or cracking is not so high, e.g. for blanking and forming of thinner, cropping, cutting harder work materials.

Properties:

DIN 2379 steel is Cold Work Steel with High Carbon High Chromium contents.
It has high wear resistant and toughness properties  DIN 2379 is the superior steels than D3 due to high alloys properties.
