THE INFLUENCE OF TECHNOLOGICAL FACTORS ON THE STRUCTURE AND RESISTANCE TO INTERGRANULAR CORROSION OF TUBES OF LOW-CARBON AUSTENITE STAINLESS STEEL

摘要

The influence of carbon content, scheme of preparation of specimens to the testing, increased of a-phase in the stock, schedules of thermal treatment on the structure and resistance to intergranular corrosion in highly oxidizing medium of hot deformed tubes of low-carbon austenite stainless steel 03Cr18Ni11 is investigated. The recommendations allowing to obtain tubes with guaranteed high resistance to intergranular corrosion during the testing according to DU, GOST 6032-89 are developed and implemented.
