Abstract
New low-nickel Cr19Ni6Mn10Mo2N steel has highest durability in the hot-rolled and tempered from austenitic area state that provides its eff ective application in the Arctic and Antarctic climatic conditions. The excess of durability over level, common for traditional stainless steel of the Cr18Ni10 type, is provided due to additional solid solution hardening. The usual Cr18Ni9 steel, alloyed by nitrogen to 0.18 %, has the smaller, but also high level of mechanical properties, diff ers in smaller thermal and mechanical stability of austenite and can be applied in less rigid on temperature and loadings service conditions.
