Improving Corrosion-Resistant Properties of Heat-Resistant Structural Steel by a Low-Temperature Chemicothermal Treatment Based on Nitriding and Nicotriding Processes

Abstract

The paper proposes a new technological process for anticorrosion steel nitriding, that consists in the saturation with the use of a catalytic atmosphere prepared based on ammonia at 540–550°C during 4–6 h and a nitrogen potential amounting to 6–6.5% of N followed by a 3-hour tempering at a temperature ranging from 300 to 400°C.

期刊介绍： Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
