Strong Match — 94.6% match
based on chemical composition and mechanical property overlap.
SAE J403 1023 (SAE J403:2014) and AISI 1025 are both steel grades.
Both fall under the Carbon Steel category.
SAE J403 1023 is typically used for chemistry-only grade; product scope as listed in the composition notes, while AISI 1025 is commonly used for forgings, shafts, general engineering.
SAE J403 1023 is defined under SAE International, originating from United States, while AISI 1025 is defined under AISI, originating from United States.
As per chemical composition, SAE J403 1023 vs AISI 1025 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.
