Strong Match — 86.4% match
based on chemical composition and mechanical property overlap.
DIN 17210 15Cr3 (DIN 17210:1986) and SAE J404 5115 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
DIN 17210 15Cr3 is typically used for low-alloy chromium case-hardening (carburizing) steel; gears, shafts, pins, and machine components requiring a hard wear-resistant carburized surface with a tough core, while SAE J404 5115 is commonly used for case hardened gears, cams, shafts.
DIN 17210 15Cr3 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while SAE J404 5115 is defined under SAE International, originating from United States.
As per chemical composition, DIN 17210 15Cr3 vs SAE J404 5115 is a 86.4% 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 86.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
