TB/T 1979-2014 Q310NQL2 steel is used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipment.
After adding phosphorus, copper, chromium, nickel and other trace elements to the steel, a dense and highly adherent protective film is formed on the surface of Q310NQL2 steel, which hinders the spread and development of rust, and protects the substrate under the rust layer to slow down its corrosion rate.
