IS 1570 (Part 2/Sec 1) 15C8 vs BS 970 (Part 3) 045A10

Close Alternative — 82.1% match based on chemical composition and mechanical property overlap.

IS 1570 (Part 2/Sec 1) 15C8 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 3) 045A10 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Carbon Steel category. IS 1570 (Part 2/Sec 1) 15C8 is typically used for boiler billets, bars and sections, welded round link chains, billets and bars for forgings, carbon steel forgings and case hardened parts (the standard links this grade to is 2100, is 6967, is 1875, is 2004, is 4432), while BS 970 (Part 3) 045A10 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) 15C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 045A10 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 1570 (Part 2/Sec 1) 15C8 vs BS 970 (Part 3) 045A10 is a 82.1% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 82.1%.
