The cause of cold bending cracking of 09CuPCrNi-B steel equivalent

The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.The Executive Standards of S355J0 steel and S355J2 steel, 09CUPCRNI-B steel equivalent are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.

12Cr1MoVG high pressure boiler tube belongs to seamless steel tube. The manufacturing method of 12Cr1MoVG high pressure boiler tube is the same as that of seamless steel tube. High pressure boiler tubes are often in high temperature and high pressure conditions when they are used. Under the action of high temperature flue gas and steam, oxidation and corrosion will occur. 09CUPCRNI-B steel equivalent, 12Cr1MoVG high pressure boiler tube is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good microstructure stability.

In the welding process, effectively preventing the stress and deformation of the component during the welding process is the key to ensuring the welding quality of the wear-resistant steel plate. In the welding process, after spot welding each part according to the position of the drawing, ensure that the size is consistent with the drawing. The welding method of symmetrical multi-layer multi-pass welding is adopted to ensure the appropriate welding process parameters, which can effectively prevent the welding deformation of the 09CUPCRNI-B steel equivalent, wear-resistant steel plate.
