This standard is a revision of JB3593-84 "Heat-treated powder metallurgy iron-based structural materials". Compared with JB3593—84, this standard only changes the material grade indication method in the original standard to the marking method according to GB/T4309—1984 "Classification and Grade Indication Method of Powder Metallurgy Materials", and the main technical performance indicators have not changed. This standard replaces JB3593—84 from the date of implementation. This standard is proposed and managed by the Technical Committee for Standardization of Powder Metallurgy Products. The main drafting unit of this standard is Beijing Powder Metallurgy Research Institute. The main drafters of this standard are Hao Rongwei, Cao Baoxing and Yin Hongyu. This standard was first issued on March 5, 1984. 1
