Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
BS 970 EN58D (BS 970:1955) and IS 1570 (Part 5) X20Cr13 (IS 1570 (Part 5):1985) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 EN58D is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 5) X20Cr13 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN58D vs IS 1570 (Part 5) X20Cr13 is a 71% 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 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
