High quality NM450 plate material manufacturer in China

P355NL1 steel tensile strength Rm:630-450MPa.If high demands are made on notch impact strength and aging resistance. It is mainly used in steam boiler and pressure vessel construction. NM450 plate material, P355NL1 plates can be processed with all known welding methods. Welding is possible both with the machine and by hand. Preheating is usually not necessary unless the outside temperature is below 5°C. Then preheating to about 150°C is recommended.

The company adopts the NM450 plate material international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety NM450 plate material management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous NM450 plate material process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for NM450 plate material and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
