Steel of austenitic class, heat and corrosion resistant. Alloyed with 17-19% Cr, 9-11% Ni, up to 2% Mn. Used in power engineering at t° ≤ 600 °C. E.g. for heat-exchange fittings of TVEL with water coolant, turbine blades, parts of compressors and pumps. Welded reactors of this alloy work in dilute solutions of acetic, nitric, phosphoric acids, saline and alkaline solutions. Parts operating under load can withstand temperatures from -196 ° C to +600 ° C, and in aggressive environments - up to +350 ° C. The substitutes are 08X22H6T, 08X17T, 08X18H8N2T, 10X14H14N4T, 12X17H9AN4, 15X25T, 12X18H9T.

Percent composition of 12X18N10T (GOST 5632-72)
Hot deformation occurs in the temperature range from 1200 °C to 850 °C. Semifinished products up to 350 mm thick are air-cooled. Weldability - without limitations. Welding methods: РДС (electrodes ЦТ-26), ЕШС and КТС. Final heat treatment is desirable. Can be processed by cutting - Kvtv. spl = 0.85 and Kvb.st. = 0.35 in the quenched state at HB 169 and σc = 610 MPa. According to corrosion properties it is close to steel 12Х18Н9Т.
