ASTM A36 vs S700MC
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).
S700MC
1.8974
The highest-strength grade in the EN 10149-2 HSLA series. 700 MPa yield with good cold formability. TMCP for ultra-fine grain structure. Used for telescopic cranes, truck frame rails, dirt-moving equipment, farm equipment, and any application requiring maximum weight reduction in cold-formed steel.
