A572 steel angle is a kind of high strength low alloy (HSLA) structural steel, which is widely used in many fields because of its excellent mechanical properties and good weldability. It has high yield strength and tensile strength, and has good impact toughness. Common grades are A572 Gr.42, A572 Gr.50 and A572 Gr.60, which correspond to different yield strength values.

1.Chemical Composition
Item | Element | Content | Effect on steel properties |
A572 Steel Angle | Carbon | <0.23% | Carbon is the main hardening element in steel, but excessive carbon content will reduce the weldability and toughness of steel. |
Manganese | ≈1.35% | Manganese can significantly improve the strength, hardness and hardenability of steel, while improving the corrosion resistance of steel. | |
Silicon | ≤0.40% | Silicon helps to improve the strength and hardness of steel, but also helps to improve the oxidation resistance and corrosion resistance of steel. | |
Phosphorus | <0.040% | Phosphorus is a harmful element in steel because it reduces the plasticity and toughness of steel. | |
Sulphur | <0.050% | Sulfur causes the “hot brittleness” of steel, which means that steel becomes brittle at high temperatures. |
