2. Product Description:How about the wear-resistant plate NM400 material? The chemical composition of NM400 wear-resistant plate has a carbon content of 4~5% and a chromium content of 25~30%. The hardness is HV1400~1800. Because the carbides are distributed perpendicular to the wear direction, the wear resistance is more than doubled even compared with the cast alloys of the same composition and hardness. NM400 wear plate is suitable for various welding methods such as submerged arc welding, manual arc welding and gas shielded welding. Low-strength welding materials are prone to low temperature cracking, so please choose low-strength soft welding materials. If the weld must be abrasion resistant, use a wear resistant welding material that matches the hardness of the upper tube in the weld. 1. Minimize hydrogen input during welding and reduce the possibility of cracking. Before welding, remove paint, rust, oil, welding slag and other stains from the welding part of the wear plate within nm400, and keep it in good condition. These stains can cause weld defects and low temperature cracks on the surface of the nm400 wear plate. Low hydrogen and ultra-low hydrogen welding consumables are recommended. Preheat nm400 wear as necessary or after welding (if required), heat preservation and resistance plate preheating include heating the weld before welding and maintaining proper interpass temperature during multi-pass welding. 2. Minimize residual stress and reduce the possibility of cracking after welding: When the weld is not filled, the residual stress is very high, so the welding must be completed continuously, and when multi-pass welding, please be careful not to cool to low at the interlayer temperature. In order to prevent the welded structure - the transition of the welded part is too strong and the weld seam is too concentrated. Make sure that the welded parts are structurally sound and that there are no gaps in the weld. Make sure that each welded section is free to shrink for as long as possible.
