Related Material — 65% match
based on chemical composition and mechanical property overlap.
SAE J403 1002 (SAE J403:2009) and GB/T 700 Q235 (GB/T 700-2006) are both steel grades.
SAE J403 1002 is classified under Carbon Steel, while GB/T 700 Q235 is classified under Structural Steel — a different category, which is worth noting alongside the chemistry match below.
SAE J403 1002 is typically used for chemistry-only grade; product scope as listed in the composition notes, while GB/T 700 Q235 is commonly used for general structural fabrication, bridges, buildings.
SAE J403 1002 is defined under SAE International, originating from United States, while GB/T 700 Q235 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, SAE J403 1002 vs GB/T 700 Q235 is a 88.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 65%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
