Why nm400 wear resistant plate quality is so important
Good NM400 wear resistant plate welding performance: Linepipe assemble is usually in the wild environment with fierce conditions, welding performance is one basic requirement for wild welding work. Corrosion resistant: gas or fluid transmitted in NM400 wear resistant plate pipelines may contain corrosive elements-S. Good moldability: for cold roll forming process is taken place before welding, good moldablity is the key to good ductility and toughness of final product.
Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.
Try to use NM400 wear resistant plate 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 wear resistant plate temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
