Application advantages of NM400 material meaning
The company adopts the NM400 material meaning 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 NM400 material meaning 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.
The seamless steel pipe for general use is rolled by common carbon structural steel, NM400 material meaning, low alloy structural steel or alloy structural steel, with the largest output. It is mainly used as the pipe or structural part for conveying fluid. According to different uses, it can be divided into three categories: a according to chemical composition and mechanical properties; B according to mechanical properties; C according to hydrostatic test. If the steel pipe supplied according to class AB is used to accept liquid pressure, hydrostatic test shall also be carried out. The seamless pipes for special purposes include seamless pipes for boiler, chemical power, geological and petroleum, etc.
Sprin steel refers to the special alloy steel used to manufacture all kinds of springs and other elastic elements. NM400 material meaning, Spring steel has excellent comprehensive performance, good surface quality, accurate shape and size. The smelting of NM400 material meaning, spring steel is very important. It is necessary to ensure excellent metallurgical quality, not only to ensure accurate chemical composition, but also to guarantee high purity. The content of sulfur, phosphorus, oxygen and nitrogen of spring steel should be low, and the uniformity and stability of spring steel should be good.
The effect of alloy elements of NM400 material meaning, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
