Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
KS D3503 SS400 (KS D 3503:2016) and GOST 19281 09G2S (GOST 19281-2014) are both steel grades.
Both fall under the Structural Steel category.
KS D3503 SS400 is typically used for structural fabrication,bridges,buildings,machinery frames,general construction,welded structures,plates,sections, while GOST 19281 09G2S is commonly used for used for bridges, pressure vessels, pipelines, structural frames, and heavy equipment components..
KS D3503 SS400 is defined under Korean Industrial Standards (KS) (South Korea).
As per chemical composition, KS D3503 SS400 vs GOST 19281 09G2S is a 64.3% match.
As per mechanical properties, the match is 2.8%.
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.
Used for bridges, pressure vessels, pipelines, structural frames, and heavy equipment components.
