Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C15 (IS 11169 (Part 1):1984) and BS 970 (Part 1) 040A10 (BS 970 (Part 1):1991) 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 BS 970 (Part 1) 040A10 is commonly used for used for bolts, studs, shafts, brackets, fabricated components, and general engineering parts..
IS 11169 (Part 1) 20C15 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 040A10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 20C15 vs BS 970 (Part 1) 040A10 is a 80% 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.
