Close Alternative — 84.9% match
based on chemical composition and mechanical property overlap.
GOST 4543 40X (GOST 4543-2016) and GOST 4543 40XH (GOST 4543-2016) 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 GOST 4543 40XH is commonly used for heavy-duty gears, transmission shafts, axles, high-strength fasteners, forged machinery parts.
As per chemical composition, GOST 4543 40X vs GOST 4543 40XH is a 82.9% match.
As per mechanical properties, the match is 94.6%.
Combined, this makes them a close alternative overall at 84.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
