Strong Match — 94.6% match
based on chemical composition and mechanical property overlap.
AISI 1025 and SAE J403 1023 (SAE J403:2014) are both steel grades.
Both fall under the Carbon Steel category.
AISI 1025 is typically used for forgings, shafts, general engineering, while SAE J403 1023 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
AISI 1025 is defined under AISI, originating from United States, while SAE J403 1023 is defined under SAE International, originating from United States.
As per chemical composition, AISI 1025 vs SAE J403 1023 is a 94.6% 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 94.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
