Related Material — 65% match
based on chemical composition and mechanical property overlap.
GOST 19281 09G2S (GOST 19281-2014) and SAE J404 50B46 (SAE J404:2009) are both steel grades.
GOST 19281 09G2S is classified under Structural Steel, while SAE J404 50B46 is classified under Alloy 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 SAE J404 50B46 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
SAE J404 50B46 is defined under SAE International (United States).
As per chemical composition, GOST 19281 09G2S vs SAE J404 50B46 is a 65% 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.
