The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality EN S420M steel plates products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

Can EN S420M steel plates, 40Cr material be replaced with 40MnB steel? 40MnB steel is used to manufacture small and medium-sized important quenched and tempered parts in tractors, automobiles and other general machinery and equipment, such as automobile half shafts, steering shafts, spline shafts, worms and machine tool spindles, gear shafts, etc. 40MnB steel can replace 40Cr material to make parts with larger cross-sections, such as the middle shaft of a hoist. And 40MnB steel can replace 40CrNi steel when making small-sized parts.

10# seamless steel pipe chemical composition : C: 0.07-0.13, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.15, Ni: 0.30, Cu: 0.25. 10# seamless steel pipe mechanical properties: recommended heat treatment temperature: 930℃, tensile strength: 335 MPa, yield strength: 205 MPa, elongation: 31%, impact energy is not required. EN S420M steel plates, 10# seamless steel pipe has high plasticity and toughness, no temper brittleness tendency, and good weldability. Its machinability under cold drawing or normalizing treatment is obviously improved. In cold state, 10# seamless steel pipe is easy to be extruded and molded, but its strength is low, and its hardenability is very poor.

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. EN S420M steel plates, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, EN S420M steel plates sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!

We have our own factory, including the production and manufacturing of steel pipes, with a special EN S420M steel plates steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect EN S420M steel plates after-sale service guarantee system, lets the customer save the worry and the labor.
