Steel 10ГН (10ГНА)
Designation
Description
10ГН steel is used: for the production of hot-rolled billets used for the manufacture of seamless hot-rolled tubes; welding wire of SV-10ГН required for submerged arc welding of structures with special requirements for performance and corrosion resistance of the welds.
Note
Mild steel, timeless steel capped aluminum.
Standards
Chemical composition
Fe is the basis.
According to TU 14-1-1251-75 and TU 14-1-1365-75 the chemical composition is presented for steel grade 10GN. In the pipe billet, deviations in the chemical composition from the regulated are allowed: for carbon ± 0.010%, for manganese ± 0.10%, for silicon ± 0.10%, for nickel ± 0.050%, for sulfur +0.005%, for phosphorus +0.005% , for copper +0,10%, for chromium +0,050%.
According to TU 14-1-2376-78, the chemical composition is presented for high-grade 10GNA steel. Deviations in chemical composition are allowed: carbon ± 0.010%, manganese ± 0.10%, silicon ± 0.10%, nickel ± 0.050%, sulfur +0.005%, phosphorus +0.005%, copper +0 , 10%, chromium + 0.05%.
