Close Alternative — 78.2% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 280M01 (BS 970 (Part 1):1983) and IS 5517 40C8 (IS 5517:1993) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 1) 280M01 is typically used for micro-alloyed carbon manganese steel for mechanical and allied engineering purposes; strength levels s, t and u are obtained without hardening and tempering (table 5)., while IS 5517 40C8 is commonly used for crankshafts, couplings, bolts, spindles, axles, gears.
BS 970 (Part 1) 280M01 is defined under British Standards (BS), originating from United Kingdom, while IS 5517 40C8 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 280M01 vs IS 5517 40C8 is a 78.2% 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 78.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
