Strong Match — 86.8% match
based on chemical composition and mechanical property overlap.
BS 970 EN3B (BS 970:1955) and IS 11169 (Part 1) 7C4 (IS 11169 (Part 1):1984) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 EN3B is typically used for general engineering, cold forming, while IS 11169 (Part 1) 7C4 is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1).
BS 970 EN3B is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 7C4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN3B vs IS 11169 (Part 1) 7C4 is a 86.8% 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 86.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
