Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10025-5 S355J2WP (EN 10025-5:2019) and ASTM A588 Grade B (ASTM A588) are both steel grades.
Both fall under the Structural Steel (Corten / Weathering) category.
EN 10025-5 S355J2WP is typically used for high-phosphorus weathering steel for enhanced patina formation, improved low-temperature toughness; containers, smokestacks, freight wagons, silos, pylons, bridges, architectural exposed structures, while ASTM A588 Grade B is commonly used for high-strength low-alloy structural steel with atmospheric corrosion resistance (weathering steel); bridges, transmission/communication towers, gusset plates, exposed structural applications.
EN 10025-5 S355J2WP is defined under European Standard (EN), originating from Europe, while ASTM A588 Grade B is defined under ASTM International, originating from United States.
As per chemical composition, EN 10025-5 S355J2WP vs ASTM A588 Grade B is a 59.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
