introduction
The chemical composition of 20mnG steel pipes includes but is not limited to carbon C, silicon Si, manganese Mn, phosphorus P, sulfur S, chromium Cr, nickel Ni and copper Cu. The contents of these elements in the chemical composition vary, with carbon ranging from 0.17 to 0.24, silicon ranging from 0.17 to 0.37, and manganese ranging from 0.7 to 1.00. In addition, the content of phosphorus and sulfur does not exceed 0.03 and 0.03 respectively, the content of chromium does not exceed 0.15, the content of nickel does not exceed 0.25, and the content of copper does not exceed 0.20. The 20mnG boiler tube performs well in terms of mechanical properties, and its tensile strength ≥ 415MPa, yield limit ≥240MPa, elongation ≥22%.
