Strong Match — 88.9% match
based on chemical composition and mechanical property overlap.
IS 1875 Class 2 (IS 1875:1992) and SAE J403 1018 (SAE J403:2014) are both steel grades.
Both fall under the Carbon Steel category.
IS 1875 Class 2 is typically used for billets, blooms, slabs and bars for general engineering forgings, while SAE J403 1018 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
IS 1875 Class 2 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1018 is defined under SAE International, originating from United States.
As per chemical composition, IS 1875 Class 2 vs SAE J403 1018 is a 88.9% 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 88.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
