Natural release of austenitic residues

        After heat treatment and quenching, it is placed outdoors to naturally release austenite residue after 15 to 20 days of wind and rain, and it is subjected to initial grinding and pickling flaw detection .

       Aft that primary grinding is proces, the mixture is placed outdoors again and naturally releases austenite residue again aft 7 to 10 days of wind blowing and rain drenching, and the fine grinding is carried out.

        Placing in a workshop for 3 to 5 days after fine grinding, naturally releasing austenite residues again, and performing secondary fine grinding and tertiary fine grinding.

        The company's bearing products, with three natural release of the core advantages, can effectively release excess austenite, improve bearing precision, and quality.
