MS Carbon Steel nm400 steel tensile strength

P265GH grade to EN10028-2 is a non-alloy quality steel with high temperature performance. The number: 1.0425. It has good plasticity, toughness, cold bending performance and welding performance. P265GH is an executive standard of the European standard boiler vessel plate is EN10028, European pressure vessel steel plate standard 265GH, and the corresponding domestic brand is 25MnG. 25MnG is a seamless steel pipe for GB 5310-2008 high pressure boiler.

When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet, NM400 steel tensile strength has good atmosphere corrosion resistance.

Try to use NM400 steel tensile strength high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the NM400 steel tensile strength temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
