The Performance requirements of low alloy structural steel, A709 grade 50 low alloy steel sheet:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.
Sulfur is a very harmful element in {keyword steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of {keyword steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
What is the difference between Q345B steel and Q345A steel? A709 grade 50 low alloy steel sheet, 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.
