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 steel NM500 coil thickness, pipeline steel are high strength, high toughness, large deformation, thick wall, high corrosion and good weldability.
What is the difference between Q345B steel and Q345A steel? steel NM500 coil thickness, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate steel NM500 coil thickness has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.
