BBN supply EN steel grade S235J2 material heat treatment

The use of low carbon steel is limited due to its low strength. The strength of the carbon steel can be greatly improved by properly increasing the manganese content in the EN steel grade S235J2 material carbon steel and adding some alloy elements such as vanadium, titanium and niobium. If the carbon content in the carbon steel is reduced and a small amount of aluminum, boron and carbide forming elements are added, the ultra-low carbon bainite can be obtained, EN steel grade S235J2 material which has high strength and good plasticity and toughness.

In recent years, in line with the development trend of iron and EN steel grade S235J2 material steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which EN steel grade S235J2 material are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The company's business philosophy: customer satisfaction is the most important measure of our work performance; employees are the company's most important wealth; the improvement of employees' quality and professional knowledge is the growth of the company's wealth; employees' welfare and living standards are the concrete embodiment of the company's business performance; product and service quality are the lifeblood of the company's development; brand is the company's products and A mirror of service; recognition of the market is the foundation of the company's survival.

Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. EN steel grade S235J2 material, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
