Experience in Making 07Kh16N4D4B Steel at AO Petrostal Metallurgical Plant
摘要
Abstract
An overview of the origin, classification, modern production technologies, chemical compositions, and physicomechanical properties of precipitation hardening steels are presented. 17-4RN steel is shown to be the most in-demand precipitation hardening martensitic steel in the domestic industry at present; it has no analogs in the practice of Russian metallurgical production. The technological process at AO Petrostal Metallurgical Plant, under which 07Kh16N4D4B steel is produced, is described.
