Standards
Chemical composition
Fe is the basis.
According to TU 108.11.847-87 the chemical composition is given for steel 26ХН3М2ФАА. In addition, the determination of the content of aluminum, antimony, lead, tin, bismuth and arsenic is carried out. The results are not delivery, but are entered in the passport.
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 +0,050%, 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.
According to TU 108.1343-85 the chemical composition is given for steel 26ХН3М2ФА. Deviations in chemical composition are allowed: by carbon ± 0.010%, by chroma ± 0.050%, by nickel -0.10%, by manganese, molybdenum and vanadium ± 0.020% each, by copper + 0.050%, by silicon + 0.050%.
