Strong Match — 97.1% match
based on chemical composition and mechanical property overlap.
SAE J403 1004 (SAE J403:2014) and IS 1570 (Part 2/Sec 1) 4C2 (IS 1570 (Part 2/Sec 1):1979) are both steel grades.
Both fall under the Carbon Steel category.
SAE J403 1004 is defined under SAE International, originating from United States, while IS 1570 (Part 2/Sec 1) 4C2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, SAE J403 1004 vs IS 1570 (Part 2/Sec 1) 4C2 is a 97.1% 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 97.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
