Close Alternative — 81.3% match
based on chemical composition and mechanical property overlap.
BS 970 EN54 (BS 970:1955) and IS 1570 (Part 5) X40Ni14Cr14W3Si2 (IS 1570 (Part 5):1985) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 EN54 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 5) X40Ni14Cr14W3Si2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN54 vs IS 1570 (Part 5) X40Ni14Cr14W3Si2 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.
