IS 1570 (Part 2/Sec 1) 85C6 vs BS 970 (Part 3) 045M10

Related Material — 69.9% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 2/Sec 1) 85C6 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 3) 045M10 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 2/Sec 1) 85C6 is typically used for cold rolled strip for springs and cold rolled medium and high carbon strip (the standard links this grade to is 2507, is 7226), while BS 970 (Part 3) 045M10 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; case hardening steel, carbon and carbon manganese (table 14). IS 1570 (Part 2/Sec 1) 85C6 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 045M10 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 1570 (Part 2/Sec 1) 85C6 vs BS 970 (Part 3) 045M10 is a 81.1% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a related material overall at 69.9%.
