ASTM A588 (Corten) vs S275J0
Side-by-side chemical composition and mechanical property comparison.
Overview
ASTM A588 (Corten)
High-strength low-alloy weathering steel. Forms a stable protective rust patina eliminating the need for paint. Cu-Cr-Ni-V composition provides 4-8x atmospheric corrosion resistance vs carbon steel. Used for unpainted bridges, architectural facades, sculptures, outdoor structures, and freight cars.
S275J0
1.0143
Structural steel with guaranteed Charpy impact at 0°C (KV >=27J). Between S235J0 and S355J0 in the strength range. ReH >=275 MPa. Very widely used in European construction: building frames, columns, beams, and general structural applications. Good weldability. Often specified as standard section material (IPE, HEA, UPN profiles).
