IS 11169 (Part 1) 15C4 vs BS 970 (Part 3) 070M55

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 15C4 (IS 11169 (Part 1):2022) and BS 970 (Part 3) 070M55 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 15C4 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 3) 070M55 is commonly used for used for springs, blades, wear plates, hand tools, shafts, and cutting components.. IS 11169 (Part 1) 15C4 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 070M55 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 1) 15C4 vs BS 970 (Part 3) 070M55 is a 65.9% 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%.
