BS 970 (Part 1) 817M40 vs IS 1570 (Part 4) 07Cr4Mo6
Related Material — 58.8% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 817M40 (BS 970 (Part 1):1983) and IS 1570 (Part 4) 07Cr4Mo6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 817M40 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 4) 07Cr4Mo6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 817M40 vs IS 1570 (Part 4) 07Cr4Mo6 is a 58.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 58.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
