The chemical composition of A572 Grade50 steel angle is C≤0.23, Si≤0.4, Mn≤1.35, P≤0.03, S≤0.025, and Nb is 0.005 - 0.05. When the thickness is >40mm, Si is 0.15 - 0.4; for every 0.01 decrease in C, Mn is allowed to increase by 0.06, with a maximum of 1.6. Reasonable chemical composition makes the steel have good comprehensive performance.
Angle steel, also known as angle iron, is a versatile structural steel product characterized by its L-shaped cross-section with two perpendicular sides. Available in equal-leg (sides of the same length) and unequal-leg (sides of different lengths) varieties, it offers exceptional strength-to-weight ratio, making it an ideal choice for diverse applications. Its robust structure enables high load-bearing capacity, while the open shape allows for easy welding, bolting, and fabrication into complex frameworks.
A36 and A572 steels have high strength, among which A572 Grade50/60/65 has higher strength and can withstand greater pressure and load, making it suitable for structural support with higher strength requirements. This enables them to ensure the stability and safety of structures in the fields of construction and engineering.
S275JR angle steel: has low yield strength, suitable for general structural purposes, and can meet the basic requirements for structural strength of common buildings, bridges and other general projects. S355JR angle steel: has high strength, suitable for structures with high loads and high stresses, and can meet the high strength requirements of tower cranes, runways and other scenes.
SS540 angle steel can be manufactured by hot working or cold working, such as hot rolling, cold working, etc., which makes it possible to make angle steel of various shapes and sizes according to different needs.
It is not easy to break or deform during processing and use, and the elongation is within a certain range, ensuring that the steel can produce a certain deformation without breaking when subjected to external forces. At the same time, it has good impact toughness and can withstand a certain degree of impact load without being easily damaged.
