Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GOST 4543 40X (GOST 4543-2016) and NF A35-565 100C6 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 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 40X vs NF A35-565 100C6 is a 65.1% match.
As per mechanical properties, the match is 18.2%.
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.
GOST 4543 40X specifies Ni, Cu which are not specified for NF A35-565 100C6.
Can GOST 4543 40X Be Substituted With NF A35-565 100C6?
GOST 4543 40X and NF A35-565 100C6 share some compositional similarity but differ enough that substitution should not be assumed. Review the differences above carefully, and consult the applicable standard or a metallurgist before using one in place of the other.
