BS 970 (Part 3) 316S33 vs IS 1570 (Part 5) X04Cr17Ni12Mo2
Strong Match — 89.4% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 316S33 (BS 970 (Part 3):1991) and IS 1570 (Part 5) X04Cr17Ni12Mo2 (IS 1570 (Part 5):1985) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 3) 316S33 is defined under British Standards (BS), originating from United Kingdom, while IS 1570 (Part 5) X04Cr17Ni12Mo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 3) 316S33 vs IS 1570 (Part 5) X04Cr17Ni12Mo2 is a 89.4% 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 89.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
