HP295 is mainly used in the manufacture of liquefied gas cylinders, its impact resistance of NM400 steel plate chemical composition is stable, P, S content is low, pure steel, the internal organization, fine grain. Moderate strength, good plasticity, low yield ratio, yield platform is not obvious, vertical and horizontal performance of small differences, excellent cold stamping performance.
The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.
As the thickness and hardness of impact resistance of NM400 steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the impact resistance of NM400 steel plate from cutting cracks, preheating should be carried out before impact resistance of NM400 steel plate cutting. Special attention should be paid to preheating to make the entire impact resistance of NM400 steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole impact resistance of NM400 steel plate cannot be preheated, the partial preheating method can be used instead.
SA537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the impact resistance of NM400 steel plate, SA537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of SA537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.
Our company will accept the product quality objection registration record, pass it to the impact resistance of NM400 steel plate production unit and relevant departments, and timely coordinate the supervision of product impact resistance of NM400 steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
