BS 970 (Part 1) 080A37 vs IS 1570 (Part 2/Sec 1) 35C8
Strong Match — 93.8% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 080A37 (BS 970 (Part 1):1983) and IS 1570 (Part 2/Sec 1) 35C8 (IS 1570 (Part 2/Sec 1):1979) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 1) 080A37 is typically used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6., while IS 1570 (Part 2/Sec 1) 35C8 is commonly used for billets and bars for forgings, carbon steel forgings, flame and induction hardened parts and hardened and tempered parts (the standard links this grade to is 1875, is 2004, is 3930, is 5517).
BS 970 (Part 1) 080A37 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 2/Sec 1) 35C8 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 080A37 vs IS 1570 (Part 2/Sec 1) 35C8 is a 93.8% 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 93.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
