A514 grade B steel material processing service

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, A514 grade B steel material based on a high starting point and high technology, the company has vigorously developed various steel products A514 grade B steel material and deep-processed parts, steel structures, precision castings, seamless pipes.

35SiMn steel can be used to manufacture parts with medium speed and medium load under the condition of quenching and tempering. 35SiMn steel can also be used to manufacture parts with high load, small impact and vibration, and parts with large cross-section and surface hardening, such as the main shaft and hub of steam turbine, impeller and various important fasteners, transmission shaft, main shaft, mandrel, connecting rod, gear, worm and trolley shaft in general machinery. In addition, A514 grade B steel material, 35SiMn steel can also be used to make thin-walled seamless steel pipe.

904L corrosion-resistant steel is developed with various sulfuric acid corrosion applications. 904L corrosion-resistant steel has high chromium content and enough nickel content. The addition of copper makes 904L corrosion-resistant steel have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking, and its pitting corrosion resistance is slightly better than other steels, such as A514 grade B steel material.

Punchability refers to the performance of metal without cracks and other defects after stamping deformation. Many steel products are manufactured through a stamping process. In order to ensure the quality of the products and the smooth progress of the process, the A514 grade B steel material, steel plates and strips used for stamping must have qualified stamping performance.
