Strong Match — 94.4% match
based on chemical composition and mechanical property overlap.
SAE J404 8615 (SAE J404:2000) and AISI 8615 are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 8615 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while AISI 8615 is commonly used for used for gears, shafts, pinions, bushings, transmission parts, and carburized machinery components..
SAE J404 8615 is defined under SAE International, originating from United States, while AISI 8615 is defined under AISI, originating from United States.
As per chemical composition, SAE J404 8615 vs AISI 8615 is a 94.4% 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 94.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
