Cairo JIS SM400A plates Supplier

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, JIS SM400A plates based on a high starting point and high technology, the company has vigorously developed various steel products JIS SM400A plates and deep-processed parts, steel structures, precision castings, seamless pipes.

The purpose of JIS SM400A plates quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of JIS SM400A plates. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

The company always adheres to the concept of green production, follows the development path of innovation, transformation and improvement, and has carried out in-depth cooperation with Zhengzhou University and other scientific research institutes, planning from a high starting point, strict standard design, and successfully implementing engineering projects With nearly 20 research and development projects, the company's production technology and equipment are at the forefront of the industry, and indicators such as environmental protection, energy consumption, cost, and resource utilization have reached the advanced level in the industry.

The carbon content of No. 55 steel is 0.55%, and the heat treatment is mostly used for quenching and tempering. The carbon content of No. 55 steel is large, and the hardness after quenching is higher (about HRC63). JIS SM400A plates, High-quality carbon structural steel 55# is a high-strength medium-carbon steel with high surface hardness and strength after treatment, but poor plasticity and toughness, medium cutting performance, poor weldability and hardenability, and water quenching can form cracks propensity.
