ASTM
A36/A36M is one of the most widely used carbon structural steel standards globally, serving as a fundamental material in construction, bridge building, machinery manufacturing, and general structural engineering.
According to the ASTM A36/A36M specification, the minimum yield strength of this steel grade is clearly regulated to ensure structural safety and reliability. For most common forms of A36 steel, including plates, bars, and standard structural shapes with thickness not exceeding 8 inches (200 mm), the minimum yield strength is set at 36 ksi (250 MPa).
For plates thicker than 8 inches (200 mm), the standard adjusts the minimum yield strength to 32 ksi (220 MPa).
ASTM A36/A36M steel yield strength, paired with a minimum tensile strength of 58-80 ksi (400-550 MPa), endows the steel with excellent ductility and toughness. This means the steel can absorb energy and deform plastically before fracturing, enhancing the resilience of structures against dynamic loads, impacts, and extreme weather conditions.
A36 steel exhibits good weldability, formability, and machinability, making it easy to process into various structural components while maintaining its mechanical properties. Unlike high-strength alloy steels.
