Related Material — 65% match
based on chemical composition and mechanical property overlap.
GOST 19281 09G2S (GOST 19281-2014) and ASTM A959 309 (ASTM A959:2011) are both steel grades.
GOST 19281 09G2S is classified under Structural Steel, while ASTM A959 309 is classified under Stainless Steel — a different category, which is worth noting alongside the chemistry match below.
GOST 19281 09G2S is typically used for used for bridges, pressure vessels, pipelines, structural frames, and heavy equipment components., while ASTM A959 309 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
ASTM A959 309 is defined under ASTM International (United States).
As per chemical composition, GOST 19281 09G2S vs ASTM A959 309 is a 65.1% 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.
