Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 25C4 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 080A20 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 25C4 is typically used for cold heading and cold extrusion of parts not heat treated after cold forming; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex a), while BS 970 (Part 1) 080A20 is commonly used for used for nuts, bolts, hydraulic fittings, precision turned parts, sleeves, and couplings..
IS 11169 (Part 1) 25C4 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 080A20 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 25C4 vs BS 970 (Part 1) 080A20 is a 72.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
