The manufacturing process and normalizing technology of S690QL high tensile 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 S690QL high tensile steel steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main S690QL high tensile steel 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.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. S690QL high tensile steel, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

The requirements for toughness impact energy of S690QL high tensile steel, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
