IS 1570 (Part 2/Sec 1) 45C8 vs BS 970 (Part 1) 080M46
Strong Match — 96.9% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 2/Sec 1) 45C8 (IS 1570 (Part 2/Sec 1):1979) and BS 970 (Part 1) 080M46 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Carbon Steel category.
IS 1570 (Part 2/Sec 1) 45C8 is typically used for billets and bars for forgings, carbon steel forgings, cold rolled strip for springs, flame and induction hardened parts, shipbuilding forgings and hardened and tempered parts (the standard links this grade to is 1875, is 2004, is 2507, is 3930, is 3261, is 5517), while BS 970 (Part 1) 080M46 is commonly used for used for crankshafts, connecting rods, spindles, gears, shafts, and machine tools..
IS 1570 (Part 2/Sec 1) 45C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 080M46 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 1570 (Part 2/Sec 1) 45C8 vs BS 970 (Part 1) 080M46 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%.
Frequently Compared With IS 1570 (Part 2/Sec 1) 45C8:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
