CSA G40.21 260WT vs EN 10025-5 S235J2W

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

CSA G40.21 260WT (CSA G40.21-13 (R2023)) and EN 10025-5 S235J2W (EN 10025-5:2019) are both steel grades. Both fall under the Structural Steel (Corten / Weathering) category. CSA G40.21 260WT is typically used for weldable structural steel with guaranteed charpy v-notch low-temperature toughness; secondary members, stair stringers, bracing in cold-climate service, while EN 10025-5 S235J2W is commonly used for weathering (atmospheric corrosion-resistant) structural steel; bridges, railway wagons, shipping containers, transmission towers, outdoor structures exposed without protective coating. CSA G40.21 260WT is defined under Canadian Standards Association (CSA), originating from Canada, while EN 10025-5 S235J2W is defined under European Standard (EN), originating from Europe.

As per chemical composition, CSA G40.21 260WT vs EN 10025-5 S235J2W is a 78.8% match. As per mechanical properties, the match is 22.2%. Combined, this makes them a minimal match overall at 35%.
