Main Characteristics

Tungsten-chrome-vanadium steel makes a reliable choice in terms of oil hardening and air. The given approach helps to increase firmness, hardenability, and heat resistance against tempering and good toughness. Steel property is not that resistant to thermal fatigue and helps to change the temperature quickly. Any of the tools cooled down through water is not right through steel. The soft-annealed state makes it right.


The tools used for hot mechanical working are the ones that are needed to insert die and small pressing die. It’s used for different products in terms of thorns and jaws, forgings for swaging, copper alloys, tools used for the production of nuts, rivets, and screws, along with different pressing discs. Additionally, it comes with a movable part in the core, mold, and other highly stressed parts to make it exceptionally perfect.
