Cryogenic treatment
1. -196°C ultra-long cryogenic treatment transformed nearly all residual austenite into martensite;
2. Precipitated nano-sized carbide particles increase hardness and toughness;
3. Improve the dimensional accuracy, wear resistance and impact toughness of the product;
4. Enhance the internal stress distribution of the product and increase the fatigue strength;
5. Improve the corrosion resistance of the workpiece.
