Strong Match — 86.8% match
based on chemical composition and mechanical property overlap.
EN 10084 17CrS3 (EN 10084:2008) and SAE J404 5115 (SAE J404:2000) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 17CrS3 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while SAE J404 5115 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
EN 10084 17CrS3 is defined under European Standard (EN), originating from Europe, while SAE J404 5115 is defined under SAE International, originating from United States.
As per chemical composition, EN 10084 17CrS3 vs SAE J404 5115 is a 86.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 86.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
