 pull stud BT40 Cryogenic treatment
1. The ultra-long cryogenic treatment at - 185 C transforms nearly all residual austenite into martensite.
2. Precipitated nano-carbide particles increase hardness and toughness.
3. Reducing residual stress;
4. The wear resistance is improved significantly.

Aging treatment
20-40 h super-long heat aging removes residual internal stress during grinding.
