Technical characteristics

Steel 37KH12N8G8MFB (ЭИ481) belongs to the group of heat-resistant high-alloy stainless steels of the austenitic class. Used for the production of control elements of the turbine disks, normalized and fasteners. The limit temperature should not be more than 650 °C, short-term is permitted up to 700 °C. In air, the steel loses its corrosion-resistant properties at temperatures which exceed 750 °C. Steel has a higher percentage of chromium and manganese, and can be made according to the technology of electroslag remelting. This steel is marked with the additional letter W.
