Structural steel quality homomorphically molybdenum.
Standards
Chemical composition
Fe is the basis.
According to GOST 4543-71 the content in high-quality steel is regulated: P≤0,025%; S≤0.025%; Сu≤0.30%; in high-grade steel: P≤0,025%; S≤0.015%; Сu≤0.25%.
According to TU 14-1-993-74 the chemical composition is given for steel grade 40ХГНМ. Permissible deviations from the norms for chemical composition: carbon ± 0.010%, manganese, chromium, molybdenum and silicon ± 0.020% each, nickel ± 0.030%, sulfur and phosphorus ± 0.0050% each.
According to TU 14-1-518-73, the total content of sulfur and phosphorus in the steel should not be more than 0.060%. In the finished rolled products, if all the requirements of the technical specifications are met, deviations from the chemical composition standards are allowed in accordance with Table 3 of GOST 4543.
