Fe is the basis.
According to TU 14-1-4461-88, the chemical composition of the steel should comply with the standards specified in Table 2 (Appendix 1), sent on request by the Central Research Institute of Chemical Technology named after Bardin. The sulfur content of sulfur is not more than 0.011%, phosphorus is not more than 0.015%, while the total content of sulfur and phosphorus should not be more than 0.022%. The residual copper content should not be more than 0.15%. With the consent of the consumer, it is allowed - up to 0.20%. The residual molybdenum content is allowed up to 0.10%. In the finished sheets the following deviations in chemical composition from the norms indicated in Table 2 are allowed: carbon + 0.02 / -0.010%; tungsten ± 0.10%; manganese, silicon, chromium and nickel ± 0.050%; molybdenum ± 0.030%; vanadium +0.020%. Partial or complete replacement of tungsten by molybdenum from the calculation of 2.5 mass fraction of tungsten is allowed with one mass fraction of molybdenum.
According to TU 14-1-1369-75, the chemical composition of the steel should correspond to the norms indicated in Table 2 (Appendix 4), sent on request. The sulfur content of sulfur is not more than 0.010%, phosphorus is not more than 0.015%, while the total content of sulfur and phosphorus should not be more than 0.022%. The residual copper content should not be more than 0.15%. With the consent of the consumer, it is allowed - up to 0.20%. The residual molybdenum content is allowed up to 0.10%. When observing mechanical properties, deviations from the chemical composition are allowed within the limits: carbon + 0.02 / -0.010% (in finished sheets); tungsten ± 0.10%; manganese, silicon, chromium and nickel ± 0.050%; molybdenum ± 0.030%; vanadium +0.020%. Partial or complete replacement of tungsten by molybdenum from the calculation of 2.5 mass fraction of tungsten is allowed with one mass fraction of molybdenum. When the tungsten is completely replaced, the molybdenum content should be in the range 0.25-0.40%; while the residual content of tungsten is allowed up to 0.20%.
According to TU 14-1-4489-88, the chemical composition of steel should comply with GOST B 25854-83. The mass fraction of sulfur in steel should not exceed 0.0150%, phosphorus - 0.020% with a total content of not more than 0.030%. If all the requirements of technical specifications are met, chemical composition deviations in the pipe blank are allowed: carbon ± 0.010%, chromium, nickel, silicon, manganese and tungsten ± 0.050%, molybdenum ± 0.030%, vanadium +0.020%. The mass fraction of copper should not be more than 0.15%. Full or partial replacement of tungsten with molybdenum is allowed at the rate of 2.5 parts by weight of tungsten is replaced by one part by weight of molybdenum. When molybdenum is completely replaced by tungsten, the mass fraction of molybdenum should be 0.30-0.40. In the case of partial replacement of tungsten with molybdenum, the actual mass fraction of tungsten is recalculated to molybdenum in a ratio of 2.5: 1 and the conventional mass fractions of molybdenum and tungsten, in terms of molybdenum, should correspond to the quoted molybdenum mass fraction when the tungsten is completely replaced. Without the replacement of tungsten by molybdenum, the residual mass fraction of molybdenum is allowed to be 0.10%. With the complete replacement of tungsten by molybdenum, a residual mass fraction of tungsten of 0.15% is allowed.
According to TU 14-1-1447-75 the sum of sulfur and phosphorus should not exceed 0.022%. It is allowed to increase the content of sulfur or phosphorus by 0.0010% with a total content of no more than 0.022%. Deviations in the established norms for the chemical composition are allowed: carbon ± 0.010%, chromium, nickel, silicon, manganese, tungsten ± 0.050%, molybdenum ± 0.030%, vanadium + 0.020%. Full or partial replacement of tungsten with molybdenum is allowed at the rate of 2.5 parts by weight of tungsten is replaced by one part by weight of molybdenum. When molybdenum is completely replaced by tungsten, the molybdenum content should be 0.30-0.40%. In the case of partial replacement of tungsten with molybdenum, the actual content of tungsten is recalculated to molybdenum in a ratio of 2.5: 1 and the conditional total molybdenum and tungsten content in terms of molybdenum should correspond to the specified molybdenum content when the tungsten is completely replaced. In steel without the replacement of tungsten by molybdenum, the residual molybdenum content of 0.10% is allowed. With the complete replacement of tungsten by molybdenum, the residual content of tungsten is allowed up to 0.15%.
According to TU 14-1-4878-90, the chemical composition of the steel must comply with the standards specified in Appendix 1, sent on request by the Central Research Institute of Chemical Technology named after Bardin. Deviations from the chemical composition are permissible: carbon ± 0.010%, chromium, nickel, silicon, manganese and tungsten ± 0.050% each, molybdenum ± 0.030%, vanadium +0.020%.
