SM490B grade steel,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.
JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with SM490B grade steel SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This SM490B grade steel alloy steel SM490B grade steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
