Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 5517 45CrSi9 (IS 5517:1993) and SAE J404 5115 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 5517 45CrSi9 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5115 is defined under SAE International, originating from United States.
As per chemical composition, IS 5517 45CrSi9 vs SAE J404 5115 is a 70.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
