9 cr2mo materials for typical Cr2 cold roll steel is mainly in the industrial used in the manufacture of cold rolled with the roller of roller of cold die and punch etc forging but many say don't know about 9 cr2mo heat treatment method, so here mainly to talk about 9 cr2mo heat treatment method, hope to be of spheroidizing annealing: 1 790 ~ 810 heating, isothermal, 650 ~ 670, 500 from air cooling;2 Quenching: Suhu pemanasan = 880 ~ 900, pendinginan pendinginan: Menurut berbagai pengampunan dan persyaratan yang berbeda, media pendingin seperti oli cairan pendinginan air PAG dapat digunakan.
CATATAN: The Forgings adalah CR2 Cold Roll Steel khas。
