BS 970 (Part 3) 080A47 vs IS 11169 (Part 1) 45C8

Strong Match — 92.9% match based on chemical composition and mechanical property overlap.

BS 970 (Part 3) 080A47 (BS 970 (Part 3):1991) and IS 11169 (Part 1) 45C8 (IS 11169 (Part 1):1984) are both steel grades. Both fall under the Carbon Steel category. BS 970 (Part 3) 080A47 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; carbon and carbon manganese steel (table 13), while IS 11169 (Part 1) 45C8 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 (Part 3) 080A47 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 45C8 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 (Part 3) 080A47 vs IS 11169 (Part 1) 45C8 is a 92.9% 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 92.9%.
