摘要
汽车齿轮钢8620H是我公司近年来开发研制的钢种,该钢要求的淬透性带很窄,纯净度要求很高。试制成功后又对8620H钢做了进一步的研究,对其在不同热处理制度下的组织和性能进行了摸索。
Gear steel 8620 H for vehicle application, which requires thinner quenched layer and higher purity, is a new steel grade developed by our company. 8620 H steel is trial- made successfully and tested in further to find out the microstructure and properties under different heat-treating conditions.
