Strong Match — 87.9% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C15 (IS 11169 (Part 1):1984) and SAE J403 1524 (SAE J403:2001) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 20C15 is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1), while SAE J403 1524 is commonly used for chemistry-only grade; product scope as listed in the composition notes.
IS 11169 (Part 1) 20C15 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1524 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 20C15 vs SAE J403 1524 is a 87.9% 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 87.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
