based on chemical composition and mechanical property overlap.
EN 10083-1 51CrV4 (EN 10083-1:1996) and SAE J404 5160 (SAE J404:2009) are both steel grades.
EN 10083-1 51CrV4 is classified under Spring Steel, while SAE J404 5160 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below.
EN 10083-1 51CrV4 is typically used for quenched and tempered machine parts (clause 1.1), while SAE J404 5160 is commonly used for automotive leaf springs, coil springs.
EN 10083-1 51CrV4 is defined under European Standard (EN), originating from Europe, while SAE J404 5160 is defined under SAE International, originating from United States.
As per chemical composition, EN 10083-1 51CrV4 vs SAE J404 5160 is a 70.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 65%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
