Related Material — 67.4% match
based on chemical composition and mechanical property overlap.
GOST 4543 40X (GOST 4543-2016) and SAE J404 50B46 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
GOST 4543 40X is typically used for gears, shafts, axles, spindles, studs, automotive 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 4543 40X vs SAE J404 50B46 is a 67.4% 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 67.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
