Hot Forging High Hardness, High Wear Resistance 7crsimnmov Flame Hardening Cold Work Die Steel
Ningshing is committed to providing customers with quality steel solutions, and we would like to introduce our newly launched HMD Flame hardening steel to you.
HMD flame hardening steel quenching temperature range is very wide, 850 ~ 1000 ° C, quenching in the temperature range of about 150 ° C, can obtain satisfactory results, so adapt to manual operation quenching, you can use oxyacetylene spray gun or other heaters, air cooling quenching after heating, after quenching can be used directly. Therefore, it has high hardenability, high surface hardness after air cooling, good performance of the heart, and small quenching deformation.
