Strong Match — 97.2% match
based on chemical composition and mechanical property overlap.
IS 6911 X07Cr17 (IS 6911:1992) and BS 970 (Part 1) 430S17 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X07Cr17 is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while BS 970 (Part 1) 430S17 is commonly used for stainless and heat resisting steel for mechanical and allied engineering purposes (table 13)..
IS 6911 X07Cr17 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 430S17 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 6911 X07Cr17 vs BS 970 (Part 1) 430S17 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.
