What is TB/T 1979 08CUPVRE steel plate?

TB/T 1979 08CUPVRE steel plate is atmospheric corrosion resistant steel for railway vehicles. Phosphorus and copper are important elements to improve the atmospheric corrosion resistance of TB/T 1979 08CUPVRE steel plate. Rare earth (RE) has many functions such as improving the fatigue strength of sodium and refining the product grain. An important role in TB/T 1979 08CUPVRE steel plate is to add RE to make phosphorus in the steel Divide evenly in the middle, so that the phosphorus’s resistance to atmospheric corrosion can be fully utilized.

Application

TB/T 1979 08CUPVRE steel plate 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 petroleum equipment.
