ENSURING THE REQUIRED STRUCTURE AND PROPERTIES OF STEEL 30HGSN2A IN THE IMPLEMENTATION OF MULTI-STAGE COMBINED PROCESSING
This article presents the results of studies of the structural features and properties of high-strength steel 30HGSN2A during the implementation of multi-stage combined processing. Such processing includes steel smelting and obtaining a deformed billet, intermediate heat treatment operations, machining, welding, final heat treatment, chromium plating. Recommended modes that will provide the required level of steel characteristics and exclude cases of premature destruction of the products.
