Product information
● Material: 42CrMo;
● Hardness: 46-50HRC;
● Grinding within the hole several times, up to Ra0.4, played a mirror effect;
● Cylindrical blank sockets adopt grinding processing technology, more suitable for high-speed processing;
● Cylindrical and end face grinding, up to Ra0.4, play a mirror effect;
● Surface "green" special coating treatment, improve the surface hardness, wear resistance, improve cleanliness, more stable accuracy, the surface is more smooth, rust, better corrosion resistance, feel more comfortable and more beautiful appearance.
● Cryogenic treatment
 1, -185 ℃ super-long cryogenic treatment, so that nearly all the retained austenite into martensite;
 2. precipitation of nano-carbide particles, increase the hardness and toughness;
 3. Reduce the residual stress;
 4. Significantly improve wear resistance.
 
Aging processing
≥ 100h ultra-long set to remove the heat aging residual stress grinding process.
