Strong Match — 89.2% match
based on chemical composition and mechanical property overlap.
SAE J404 4135 (SAE J404:2000) and JIS G4105 SCM435 (JIS G4105:1979) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 4135 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while JIS G4105 SCM435 is commonly used for gears, shafts, high tensile bolts.
SAE J404 4135 is defined under SAE International, originating from United States, while JIS G4105 SCM435 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, SAE J404 4135 vs JIS G4105 SCM435 is a 89.2% 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 89.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
