Technical characteristics

Medium-carbon stainless steel 45KH14N14V2M (ЭИ69) belongs to the group of heat-resistant high-alloy austenitic steels. Used for the production of standardized items, valves and pipelines, which operate under conditions of pumping of aggressive liquid or gaseous media at temperatures up to 600 °C. Limited use considering the steel to temperatures of 650…750°C. Steel is also used in the manufacture of the working parts of automobile engines.
