Strong Match — 91.4% match
based on chemical composition and mechanical property overlap.
SAE J404 1340 (SAE J404:2000) and SAE J404 1345 (SAE J404:2000) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 1340 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while SAE J404 1345 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
SAE J404 1340 is defined under SAE International, originating from United States, while SAE J404 1345 is defined under SAE International, originating from United States.
As per chemical composition, SAE J404 1340 vs SAE J404 1345 is a 91.4% 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 91.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
