Minimal Match — 40.6% match
based on chemical composition and mechanical property overlap.
GOST 4543 40HM (GOST 4543-2016) and EN 10028-2 10CrMo9-10 (EN 10028-2:2017) are both steel grades.
Both fall under the Alloy Steel category.
GOST 4543 40HM is typically used for used for gears, shafts, spindles, bolts, and hydraulic components., while EN 10028-2 10CrMo9-10 is commonly used for flat products for pressure purposes.
EN 10028-2 10CrMo9-10 is defined under European Standard (EN) (Europe).
As per chemical composition, GOST 4543 40HM vs EN 10028-2 10CrMo9-10 is a 60.9% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 40.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
