Corten A corrosion resistant structural steel flat bars thickness is more than 300mm

With the development of remote oil and gas fields, polar oil and gas fields, offshore oil and gas fields and acid oil and gas fields, oil and gas pipeline engineering is facing challenges of high-pressure transmission and harsh environment such as low temperature, large displacement, deep sea and acid medium. In order to ensure the enthusiasm and safety of pipeline construction and operation, the basic requirements and development trend of Corten A corrosion resistant structural steel flat bars, pipeline steel are high strength, high toughness, large deformation, thick wall, high corrosion and good weldability.

The effect of alloy elements of Corten A corrosion resistant structural steel flat bars, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
