Excellent polishing and machining performance;
The ex-factory state has been pre-hardened to 3 1-37HRC, and no heat treatment is needed;
Subsequent nitriding treatment can be carried out, and the material has excellent toughness;
Excellent surface strength and wear resistance can reduce surface failure, and can also be surface treated (such as chromium plating).
This is a patented steel grade of Datong, Japan, and there is no corresponding brand in China for the time being.
