Gradient alloy nut die

Please provide the die surface, hardness of tungsten steel and wire material, and inform the failure of the die and the location of the damage, so that we can adjust the design gradient layer (partial decarbonization treatment).

What is graded alloy?

Gradient alloy is the high performance cemented carbide with multi-layer gradient structure. In nature, bones of the animals are the type of gradient structure with hard outside and soft inside.

This principle is able to effectively solve the obstacle that the material with single hardness is apt to be damaged. When the tungsten steel material is subjected to impact, the impact stress is rapidly released and buffered.
