1.2367 (DM3X)

Developed instead of 2365, it is the steel preferred in manufacturing where high temperature

resistance is required. It provides both higher hardness and higher wear resistance.

Categories: , ,
Description

Its mechanical properties at high temperatures are better than 2343 and 2344.

For example, it provides a longer working time in copper and brass extrusion

dies compared to others. It is also produced by EFS and ESR method.

 

1.2367 (DM3X) X38CrMoV5-3 Hot Work Tool Steel

APPLICATION AREAS

APPLICATION AREAS

It can be used with superior performance in all applications where 1.2365 steel is used.

An excess of 2% chromium means less high-temperature wear.

The hardness of use can be 1 – 2 Rc more.
