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 A588 Gr K structural steel plate 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 ℃.
As the tungsten content increases, the strength and toughness of the NM360 wear-resistant steel plate increase. When the mass fraction of tungsten exceeds 1.06%, the toughness decreases due to the increase in the amount of carbide precipitation. This is because tungsten combines with carbon atoms in the NM360 wear-resistant plate to form a short-range ordered C-w atom pair bond structure. The C-w atomic bond is stronger than the C-Mn and C-Fe atomic bonds. Therefore, after adding tungsten to the NM360 wear-resistant steel plate, cracks will be formed, and the energy required to break the atomic bond will be greatly increased. The toughness and strength of A588 Gr K structural steel plate, NM360 wear-resistant steel plate treated with water toughening treatment will also be significantly improved.
