Alloy Steel impact resistance of nm400 steel plate Plate Thickness

The company attaches great importance to systematic management, and has passed the impact resistance of NM400 steel plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on impact resistance of NM400 steel plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

impact resistance of NM400 steel plate, Q345 angle steel has two kinds: unequal angle steel (two sides are not the same size) and equal angle steel (two sides are the same size). impact resistance of NM400 steel plate, Q345 angle steel is widely used for mechanical processing, building structure, steel structure, etc.. In addition, Q345 angle steel can withstand - 40℃ low temperature at least and can be used in cold areas. The weight calculation formula of Q345 angle steel: 0.00785 * (side width + side width - side thickness) * side thickness, the value obtained is the weight per meter, and then multiplied by the length to calculate the weight of a piece.

NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product impact resistance of NM400 steel plate is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following impact resistance of NM400 steel plate basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.

S355NL steel plate is under EN10111 standard. We can regard impact resistance of NM400 steel plate, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE
