Related Material — 63.1% match
based on chemical composition and mechanical property overlap.
GB/T 700 Q235C (GB/T 700:2006) and ASTM A1008 SS Grade 80 (ASTM A1008) are both steel grades.
Both fall under the Structural Steel category.
GB/T 700 Q235C is typically used for hot rolled structural sheets, strips, sections and bars for welding, riveting and bolting engineering, while ASTM A1008 SS Grade 80 is commonly used for cold-rolled high-strength structural steel sheet, higher strength grade; automotive structural/reinforcement components, cold-formed high-strength parts.
GB/T 700 Q235C is defined under Guobiao Standards (GB/T), originating from China, while ASTM A1008 SS Grade 80 is defined under ASTM International, originating from United States.
As per chemical composition, GB/T 700 Q235C vs ASTM A1008 SS Grade 80 is a 94.7% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a related material overall at 63.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
