A53 Carbon Steel Square Bar

A53 carbon steel square bar is a square cross-section steel produced according to the A53 standard. It is a typical carbon steel material with a moderate carbon content (about 0.3%) and has both strength and toughness. Its tensile strength is ≥415MPa, yield strength is ≥240MPa, mechanical properties are excellent, weldability is good, and it is suitable for low-pressure fluid transportation and mechanical structures. The surface can be hot-rolled or galvanized, and is widely used in building support, pipeline systems, petrochemical and power industries. It is a basic material with both economy and reliability.
