Close Alternative — 81.3% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 897M39 (BS 970 (Part 1):1991) and IS 5517 40Cr13Mo10V2 (IS 5517:1993) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 897M39 is defined under British Standards (BS), originating from United Kingdom, while IS 5517 40Cr13Mo10V2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 897M39 vs IS 5517 40Cr13Mo10V2 is a 81.3% 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 81.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
