FIELD: metallurgy.
SUBSTANCE: steel contains the following components, wt%: up to 0.20 C, 2.0 - 6.0 Mn, up to 2.0 Si, 16.0 - 23.0 Cr, 5.0 -7.0 Ni, up to 3.0 Mo, up to 3.0 Cu, 0.1 - 0.35 N, up to 4.0 W, up to 0.01 B, up to 1.0 Co, iron and admixtures - balance. Steel has a ferrite number making below 11, the temperature value MD30, characterising resistance to formation of martensite, making below -10°C, the value of equivalent number of resistance to point corrosion PREW, making from more than 26 to 30.
EFFECT: steel has higher corrosion resistance and good moldability.
