Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
SAE J404 4140 (SAE J404:2009) and NF A35-565 100C6 are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 4140 is typically used for gears, shafts, dies, bolts, crankshafts, while NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
SAE J404 4140 is defined under SAE International, originating from United States, while NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF), originating from France.
As per chemical composition, SAE J404 4140 vs NF A35-565 100C6 is a 67.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
SAE J404 4140 specifies Mo which is not specified for NF A35-565 100C6.
Can SAE J404 4140 Be Substituted With NF A35-565 100C6?
SAE J404 4140 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.
