ASTM A36 vs S500MC
Side-by-side chemical composition and mechanical property comparison.
Overview
ASTM A36
K02600
The most common structural carbon steel in the US. Low carbon content with good weldability and machinability. Used for buildings, bridges, construction equipment, and general structural purposes. Minimum yield strength 36 ksi (250 MPa).
S500MC
1.0984
High-strength low-alloy (HSLA) hot-rolled steel for cold forming. Thermomechanically rolled for fine grain structure. 500 MPa yield strength with excellent cold formability. Used for automotive chassis, truck frames, crane booms, and agricultural equipment.
