NM400 steel chemical element carbon steel heavy plate

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of NM400 steel chemical element steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main NM400 steel chemical element production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Marine steel is widely used in all kinds of ships and offshore platforms, but it also puts forward higher and higher requirements for marine steel. In general, the demand share of NM400 steel chemical element high-strength marine steel continues to increase. In terms of strength requirements, with the change of ship's large-scale, safety and coating specifications, the general trend is that the consumption of ordinary strength grade A marine steel plate is gradually reduced, and the consumption of high-strength marine steel plates is increased.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, NM400 steel chemical element, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled NM400 steel chemical element products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the NM400 steel chemical element rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
