Close Alternative — 80.1% match
based on chemical composition and mechanical property overlap.
EN 10025-2 S275JR (EN 10025-2:2019) and GB/T 700 Q275B (GB/T 700:2006) are both steel grades.
Both fall under the Structural Steel category.
EN 10025-2 S275JR is typically used for general structural work, bridges, machinery frames, while GB/T 700 Q275B is commonly used for hot rolled structural sheets, strips, sections and bars for welding, riveting and bolting engineering.
EN 10025-2 S275JR is defined under European Standard (EN), originating from Europe, while GB/T 700 Q275B is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, EN 10025-2 S275JR vs GB/T 700 Q275B is a 89.1% match.
As per mechanical properties, the match is 62.2%.
Combined, this makes them a close alternative overall at 80.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
