Correct welding method for nm400 wear resistant plate

Carbon steel SA516Gr70 corresponding material is SA516 Gr485 steel. SA516 Gr485 is called according to the min. tensile strength 485MPa. Our company can supply NM400 wear resistant plate, ASME SA516Gr70 carbon steel plate and sheet with thickness ranging from 5mm to 150mm. SA516Gr70 steel plate for pressure vessels and boiler is delivered in hot rolling, controlled rolling, normalizing, while plate thickness greater than 40mm must be normalizing.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and NM400 wear resistant plate heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported NM400 wear resistant plate to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

The NM400 wear resistant plate steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the NM400 wear resistant plate internal quality of the steel.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with NM400 wear resistant plate, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

Our company will accept the product quality objection registration record, pass it to the NM400 wear resistant plate production unit and relevant departments, and timely coordinate the supervision of product NM400 wear resistant plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
