Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GOST 4543 15H2NM (GOST 4543-2016) and NF A35-565 100C6 are both steel grades.
Both fall under the Alloy Steel category.
GOST 4543 15H2NM is typically used for used for heavy-duty gears, shafts, couplings, bearings, and transmission parts., while NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF) (France).
As per chemical composition, GOST 4543 15H2NM vs NF A35-565 100C6 is a 60.4% match.
As per mechanical properties, the match is 52.5%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
