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.

Chemical composition of GOST 5632−82

Notes. In 37KH12N8G8MFB steel-ø the minimum percentage of titanium may not be less than 0.08%. The content of niobium is set by calculation.
