1.2379 Stock Material

High Wear Resistance 1.2379 Stock Material

A high carbon, high chromium, air-hardening cold work tool steel with a heat treatable hardness of 60–62 HRC is 1.2379 stock material. Because there are a lot of carbides in the micro-structure of 1.2379, it has outstanding wear and abrasion resistance. Long production cold work applications needing very high wear resistance and great compression strength frequently employ 1.2379 stock material. It is machinable in the annealed state and heat treats with little distortion, similar to other air-hardening tool steels. De-carb-free rounds, flats, and squares, as well as flat ground stock and drill rods, are all forms of 1.2379 stock material.

How Do We Produce 1.2379 Material?

Electric arc furnace (EAF) melting: This process is also known as primary melting. Its foundation is the melting of metal chips obtained from suppliers and milling activities. In essence, EAF melting uses scraps from different metal processing methods. Electric arc furnace melting is common because it has low production costs.

Remelting of electro slag is another name for electro slag refining, or ESR for short. The process involves a gradual melting of the metal. The produced ingots are free of any evident faults and have acceptable surface quality for 1.2379 stock material.

What are the Uses?

This grade of tool steel is well-liked by toolmakers and is what you can use in a variety of applications for creating tools. Punching and blanking die for hard abrasive materials, such as brass, copper, zinc, and stainless steel sheet, are frequently can use.
