Close Alternative — 82.4% match
based on chemical composition and mechanical property overlap.
NF A35-552 35CD4 (NF A35-552:1986) and SAE J404 4137 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
NF A35-552 35CD4 is typically used for gears, shafts, axles, connecting rods, high strength bolts, automotive parts, while SAE J404 4137 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
NF A35-552 35CD4 is defined under Association Francaise de Normalisation (NF), originating from France, while SAE J404 4137 is defined under SAE International, originating from United States.
As per chemical composition, NF A35-552 35CD4 vs SAE J404 4137 is a 82.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
