Fe is the basis.
According to GOST 977-88 the content of V (vanadium) is calculated.
According to OST 5R.9285-95, the content of chromium up to 0.50% and molybdenum up to 0.12% is not a defect sign provided that the requirements of the standard are observed and if there are no special instructions in the technical conditions of the order or drawing. Vanadium is introduced by calculation. In the case of steel smelted in the main electric furnaces as cold-resistant (technical conditions of the order or requirements of the drawing), the sulfur and phosphorus content should not be more than 0.020% of each. As agreed by the manufacturer with the developer OST 5P.9285-95 (CRI "Prometey"), the content of sulfur and phosphorus is allowed up to 0.030% of each.
In steel smelted in an open-hearth furnace, the carbon content is allowed not more than 0.12%, the content of sulfur and phosphorus is not more than 0.035% of each.
According to OST 5P.9125-84 the chemical composition is given for steel 08GDNF. In the steel is introduced 0.8-1.0 kg of aluminum per ton of liquid metal (calculated).
According to TU 108.1273-84, deviations are allowed: for carbon + 0.020%, for silicon + 0.10 / -0.05%, for manganese ± 0.15%, for nickel ± 0.15, for copper ± 0.15% for chromium + 0.10%, for vanadium ± 0.020%.

Weldability Welded without any restrictions. The welding process - SMAW. With a significant amount of welding it is recommended that subsequent vacation.
Propensity to temper brittleness Tend not.
Flock-sensitive sensitivity not sensitive.
Defect welding Welding defects of castings after cutting is usually carried out without prior and concomitant heating. By semiautomatic welding in carbon dioxide environment used welding wire SV-08G2S diameter of 2 mm at a current of 380-420 A. Welding defects by manual welding is done with electrodes type e-50A (GOST 9467) brand SSSI-13/55. When the welding of defects of samples with a volume of more than 10000 cm3 you need to make thinning after filling half of the sample.
