Export S275N carbon steel material to Zambia

S275N carbon steel material,40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ～ 60mm when water quenching, and Ф15 ～ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ～ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.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, based on a high starting point and high technology, the company has vigorously developed various steel products and deep-processed parts, steel structures, precision castings, seamless pipes,S275N carbon steel material.S355NC steel offers excellent bending, flanging, cold-bordering and folding properties in both longitudinal and transverse direction The bending radii specified below should be observed as minimum values,S275N carbon steel material.S275N carbon steel material,The mechanical properties of boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.S275N carbon steel material
