ASTM A588 Grade A vs EN 10025-5 S355J2WP

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

ASTM A588 Grade A (ASTM A588) and EN 10025-5 S355J2WP (EN 10025-5:2019) are both steel grades. Both fall under the Structural Steel (Corten / Weathering) category. ASTM A588 Grade A is typically used for high-strength low-alloy structural steel with atmospheric corrosion resistance (weathering steel); bridges, transmission/communication towers, gusset plates, exposed structural applications, while EN 10025-5 S355J2WP is commonly used for high-phosphorus weathering steel for enhanced patina formation, improved low-temperature toughness; containers, smokestacks, freight wagons, silos, pylons, bridges, architectural exposed structures. ASTM A588 Grade A is defined under ASTM International, originating from United States, while EN 10025-5 S355J2WP is defined under European Standard (EN), originating from Europe.

As per chemical composition, ASTM A588 Grade A vs EN 10025-5 S355J2WP is a 66.9% match. As per mechanical properties, the match is 0%. Combined, this makes them a minimal match overall at 35%.
