BS 970 (Part 1) 347S31 vs IS 11169 (Part 2) X04Cr18Ni10Ti
Strong Match — 100% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 347S31 (BS 970 (Part 1):1983) and IS 11169 (Part 2) X04Cr18Ni10Ti (IS 11169 (Part 2):1989) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 347S31 is typically used for austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (table 14, with table 15 for the cold drawn condition)., while IS 11169 (Part 2) X04Cr18Ni10Ti is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars (clause 1.1).
BS 970 (Part 1) 347S31 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 2) X04Cr18Ni10Ti is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 347S31 vs IS 11169 (Part 2) X04Cr18Ni10Ti is a 100% 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 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
