Professional EN steel grade S275JR plates material supplier

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.EN steel grade S275JR plates,BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.EN steel grade S275JR plates,Superior process production line advantage sdf: The company has focused on weathering steel , pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the alloy wear-resistant steel plate is significantly improved,EN steel grade S275JR plates.EN steel grade S275JR plates,Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc We are provided best packing for structural steel plates to avoid rust Our after-sales service team will contact you if you have any question,EN steel grade S275JR plates.
