The difference in cutting processing of nm400 mechanical properties with different thickness

Quenching Improve the hardness of NM400 mechanical properties steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of NM400 mechanical properties steel and comprehensive mechanical properties.

The boiler steel pipe has excellent anti-oxidation and corrosion performance: the general steel pipe is easy to be corroded under high temperature and produces harmful substances, but the boiler steel pipe has no such worries. The high-precision material and wall thickness of the boiler steel pipe can effectively prevent the corrosion. Good tensile strength of NM400 mechanical properties, boiler steel pipe: it can keep the original state well without affecting its quality after being heated and stretched.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products NM400 mechanical properties are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.

In 2019, through the concerted cooperation of the enterprise team, the sales volume has grown steadily, and the annual sales volume has exceeded 300 million yuan. For this reason, both the investors and employees of the enterprise have received satisfactory returns. With strong development potential and brand advantages, we have always been committed to "integrity, efficiency, pragmatism, dedication" corporate spirit, dedication to society, and return to the public.
