Strong Match — 87.8% match
based on chemical composition and mechanical property overlap.
SAE J404 5115 (SAE J404:2000) and JIS G4104 SCr415 (JIS G 4104:1979) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 5115 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while JIS G4104 SCr415 is commonly used for case hardened gears, cams, pins.
SAE J404 5115 is defined under SAE International, originating from United States, while JIS G4104 SCr415 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, SAE J404 5115 vs JIS G4104 SCr415 is a 87.8% 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 87.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
