Mechanical properties and extended impact analysis of A572MGr50 Steel plate

1, A572Gr50, full name: high strength low alloy niobium vanadium structural steel plate.

2, the implementation of standard ASTM A572/A572M

3, delivery status: hot rolling or normalizing + tempering, the specific delivery status should be indicated in the warranty.

4, A572Gr50 chemical composition:

Effect of CHEMICAL composition of S and P in A572Gr50 steel plate on the properties of steel plate

Phosphorus (P): in general, phosphorus is a harmful element in steel, it increases the cold brittleness of steel, so that the welding performance deteriorates, reducing plasticity so that the cold bending performance deteriorates. Therefore, phosphorus content in steel is usually less than 0.045%, and high-quality steel is required to be lower.

Sulfur (S): Sulfur is also a harmful element in general. It makes the steel produce hot brittleness, reduces the ductility and toughness of the steel, and causes cracks in forging and rolling. Sulfur is also detrimental to welding performance, reducing corrosion resistance. Therefore, sulfur content is generally required to be less than 0.055%, and high-quality steel is required to be less than 0.040%. Adding 0.08-0.20% sulfur to steel improves machinability, usually called free cutting steel.
