Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
BS 970 EN51 (BS 970:1955) and IS 6911 X30Cr13 (IS 6911:1992) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 EN51 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars., while IS 6911 X30Cr13 is commonly used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1).
BS 970 EN51 is defined under British Standards (BS), originating from United Kingdom, while IS 6911 X30Cr13 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN51 vs IS 6911 X30Cr13 is a 73.3% 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.
