Strong Match — 97.2% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 430S17 (BS 970 (Part 3):1991) and IS 6911 X07Cr17 (IS 6911:1992) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 3) 430S17 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; ferritic stainless steel (table 17), while IS 6911 X07Cr17 is commonly used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1).
BS 970 (Part 3) 430S17 is defined under British Standards (BS), originating from United Kingdom, while IS 6911 X07Cr17 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 3) 430S17 vs IS 6911 X07Cr17 is a 97.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 97.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
