Hot rolled NM400 material meaning sheet specification

NM400 material meaning, NM series wear-resistant plates combine high hardness, high strength and high toughness, suitable for those severely worn occasions. The high wear resistance of the wear plate extends the service life of dump truck bodies, excavator buckets, crushers and similar equipment. The hardness of the wear-resistant steel plate is obtained through an effective quenching process. This method can not only achieve higher hardness, but also maintain a lower alloy composition in the steel. The produced wear-resistant plates are easy to machine, twist and weld.

NM400 material meaning, High-strength steel plates are widely used in many industries such as construction, automobiles, ships, machinery and equipment, but high-strength steel plates must be selected appropriately. First, the grade is too high, which means that the price will be high because of the high manufacturing cost. Second, the low level means that the safety performance cannot meet the standard. Third, we must strictly follow the design drawings to select high-strength steel plates specifications. Fourth, it is advised the purchaser to test the high-strength steel plates with special equipment.

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

In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This NM400 material meaning production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate NM400 material meaning size.
