Новая малоникелевая сталь Х19Н6Г10АМ2 отличается наиболее высоким уровнем прочности в горячекатаном и закаленном из аустенитной области состоянии, что обеспечивает ее эффективное применение в климатических условиях Арктики и Антарктики. Превышение прочности над уровнем, характерным для традиционной коррозионностойкой стали типа Х18Н10, обеспечивается за счет дополнительного твердорастворного упрочнения. Легированная азотом до 0,18 % обычная сталь Х18Н10 имеет меньший, но также высокий уровень механических свойств, отличается более низкой термической и механической стабильностью аустенита и может быть применена в менее жестких по температуре и нагрузкам условиях эксплуатации.

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.
