EN10025-4 steel S355ML hardenability

High temperature (creep temperature above) boiler steel plate, generally indicates low alloy heat-resistant steel EN10025-4 steel S355ML, the commonly used are chrome molybdenum steel, chrome molybdenum vanadium steel, chrome molybdenum tungsten steel, etc. For example, 15CrMoG and 12Cr1MoVG boiler steel plate in GB713 and gr 22 and gr 91 boiler steel plate in ASME SA387/SA387M. High temperature boiler steel plate EN10025-4 steel S355ML is mainly used to manufacture high temperature pressure parts such as high temperature header end cover, steam pipe plug plate, etc.

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, EN10025-4 steel S355ML weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

For stainless steel plate cutting, the choice of cutting method is determined by the thickness of steel plate. If the thickness of EN10025-4 steel S355ML stainless steel plate is more than 20 mm, flame cutting is adopted, while the thin plate is suitable for plasma cutting. In addition, if the cutting requirements are relatively high, laser cutting can be used. In addition, if the EN10025-4 steel S355ML stainless steel plate is used as a billboard, plasma cutting is adopted, Because it uses thin plates.
