Steel 12ХГНМФ
Designation
Description
12ХГНМФ steel is used: for the production of hot-rolled strip intended for the manufacture of rolled pressure vessels operating at a temperature of 450−560 °C.
Standards
Chemical composition
Fe is the basis.
In the finished rolled products according to TU 14-1-3226-81 the following deviations in chemical composition are allowed: by carbon ± 0.020%, by chromium ± 0.050%, by nickel ± 0.050%, by molybdenum + 0.050 / -0.10%, by vanadium +0.050%. The technological addition of cerium is allowed up to 0.10% (by calculation) to improve the quality of steel.
