Close Alternative — 82.9% match
based on chemical composition and mechanical property overlap.
AISI 5140 and SAE J404 5132 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
AISI 5140 is typically used for used for gears, shafts, spindles, bolts, machinery parts, and automotive components., while SAE J404 5132 is commonly used for high-tensile bolts, studs, shafts and engineering components requiring surface hardness.
AISI 5140 is defined under AISI, originating from United States, while SAE J404 5132 is defined under SAE International, originating from United States.
As per chemical composition, AISI 5140 vs SAE J404 5132 is a 82.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
