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

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

IS 11169 (Part 1) 45C8 (IS 11169 (Part 1):1984) and BS 970 (Part 3) 080A47 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 45C8 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 3) 080A47 is commonly 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). IS 11169 (Part 1) 45C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 080A47 is defined under British Standards (BS), originating from United Kingdom.

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