ASTM A36 vs S355J2
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).
S355J2
1.0577
High-strength structural steel with impact testing at -20°C (J2). Higher toughness than S355JR (tested at +20°C). Used for bridges, crane structures, offshore platforms, and cold-weather applications where impact toughness at sub-zero temperatures is required.
