Strong Match — 99.6% match
based on chemical composition and mechanical property overlap.
AISI 8615 and SAE J404 8615 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
AISI 8615 is typically used for used for gears, shafts, pinions, bushings, transmission parts, and carburized machinery components., while SAE J404 8615 is commonly used for used for gears, pinions, shafts, bushings, transmission parts, and heavy-duty machinery components..
AISI 8615 is defined under AISI, originating from United States, while SAE J404 8615 is defined under SAE International, originating from United States.
As per chemical composition, AISI 8615 vs SAE J404 8615 is a 99.6% 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 99.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
