BS 970 (Part 1) 070M26 vs IS 1570 (Part 2/Sec 1) 25C8

Strong Match — 96.9% match based on chemical composition and mechanical property overlap.

BS 970 (Part 1) 070M26 (BS 970 (Part 1):1983) and IS 1570 (Part 2/Sec 1) 25C8 (IS 1570 (Part 2/Sec 1):1979) are both steel grades. Both fall under the Carbon Steel category. BS 970 (Part 1) 070M26 is typically used for wrought steel for mechanical and allied engineering purposes; supplied in the normalized condition (table 2)., while IS 1570 (Part 2/Sec 1) 25C8 is commonly used for billets and bars for forgings, carbon steel forgings, flame and induction hardened parts, hardened and tempered parts and welded round link chains (the standard links this grade to is 1875, is 2004, is 3930, is 5517, is 6967). BS 970 (Part 1) 070M26 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 2/Sec 1) 25C8 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 (Part 1) 070M26 vs IS 1570 (Part 2/Sec 1) 25C8 is a 96.9% 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 96.9%.
