20Mn2 steel is used to manufacture carburized parts with low requirements on the surface and core, and with a cross-sectional diameter of less than 50mm, such as carburized pinions, small shafts, and low-demand pistons instead of 20Cr steel in the manufacture of automobiles, tractors and machine tools Pins, cross pin heads, diesel engine sleeves, valve jacks, gearbox levers, steel sleeves, etc. In addition, this kind of steel can also be used to make riveting weldments, screws, nuts, etc. under hot rolling and normalizing conditions.

20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for hardness of a516 grade 70 steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.

Corrosion resistance mechanism of hardness of a516 grade 70, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.
