Steel 30ХН3М1ФА (30ХН3М1Ф)
Designation
Description
30ХН3М1ФА steel is used: for the manufacture of forged billets for rotors of troubleproof; rotor shafts of the high pressure cylinder (HPC).
Note
Structural steel high-quality hromonikelemolibdenovyh.
Standards
Chemical composition
Fe is the basis.
According to TU 108.11.918-87, the chemical composition is given for steel grade 30ХН3М1ФА. Steel smelting should be carried out using an out-of-furnace refining and evacuation plant (OVRV) and carbon steel deoxidation. Cast ingots should be made in a vacuum.
According to TU 108.11.889-87, deviations in chemical composition are allowed: by carbon ± 0.010%, by chroma ± 0.050%, by manganese ± 0.020%, by molybdenum ± 0.020%, by vanadium ± 0.020%, by nickel -0.10% , for silicon +0,020%, for copper +0,050%. The total content of sulfur and phosphorus should not be more than 0.036% for smelting by a duplex process and in an electric furnace. The sulfur and phosphorus content after the use of the out-of-furnace refining and evacuation unit (OVPV) should not be more than 0.010% and 0.012%, respectively, for a sum of sulfur and phosphorus not more than 0.020%. The steel shall be melted according to the manufacturer's technical documentation using the UVRB unit. It is allowed to melt steel in an open-hearth furnace by a duplex process or in the main electric arc furnace.
