Advantages 1. Wear resistance is 6-7 times the ordinary carbon steel; 2 impact strength of ABS 4 to 5 times; 3. Self-lubricating performance is superior; 4. Strong corrosion resistance, high chemical technology; 5. non-stick phase is not easy to attach the product surface and other materials; 6. impact energy absorption strong; 7. healthy non-toxic, low temperature resistance, also in the liquid nitrogen ductility.
