Selected high-quality raw materials: 65Mn
After heat treatment and infiltration treatment, the strength is higher, and it has certain flexibility and plasticity.
More than ten high-precision manufacturing processes are carefully manufactured;
Reject false bids and strictly test! Accuracy can reach 0.008mm
1) single time, 12 hours. -185 ℃. and ultra long cryogenic treatment make the nearly all retained austenite change to martensite.
2) the precipitated nano carbide particles increase the hardness and toughness of the material.
3) remove the internal stress of the residual material.
4) after cryogenic treatment, the wear resistance of products is significantly improved, and the accuracy and service life of repeat clamping can be increased by about 50%
