Close Alternative — 76.2% match
based on chemical composition and mechanical property overlap.
EN 10025-2 S355K2 (EN 10025-2:2019) and GB/T 700 Q275A (GB/T 700:2006) are both steel grades.
Both fall under the Structural Steel category.
EN 10025-2 S355K2 is typically used for hot rolled products of structural steels, while GB/T 700 Q275A is commonly used for hot rolled structural sheets, strips, sections and bars for welding, riveting and bolting engineering.
EN 10025-2 S355K2 is defined under European Standard (EN), originating from Europe, while GB/T 700 Q275A is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, EN 10025-2 S355K2 vs GB/T 700 Q275A is a 92.3% match.
As per mechanical properties, the match is 43.9%.
Combined, this makes them a close alternative overall at 76.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
