Strong Match — 94.6% match
based on chemical composition and mechanical property overlap.
SAE J403 1023 (SAE J403:2009) and IS 1570 (Part 2/Sec 1) 25C4 (IS 1570 (Part 2/Sec 1):1979) are both steel grades.
Both fall under the Carbon Steel category.
SAE J403 1023 is defined under SAE International, originating from United States, while IS 1570 (Part 2/Sec 1) 25C4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, SAE J403 1023 vs IS 1570 (Part 2/Sec 1) 25C4 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.
