ASTM A36 vs S460NL
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).
S460NL
1.8903
High-strength normalized fine-grain structural steel with 460 MPa yield and impact testing at -50°C. The highest-strength grade in the EN 10025-3 normalized series. Used for offshore platforms, wind turbine towers, arctic bridges, cranes, and heavy steel structures in cold climates.
