BS 970 (Part 1) 410S21 vs IS 11169 (Part 2) X12Cr13
Strong Match — 94.9% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 410S21 (BS 970 (Part 1):1983) and IS 11169 (Part 2) X12Cr13 (IS 11169 (Part 2):2023) are both steel grades.
Both fall under the Stainless Steel category.
BS 970 (Part 1) 410S21 is typically used for stainless and heat resisting steel for mechanical and allied engineering purposes (table 13)., while IS 11169 (Part 2) X12Cr13 is commonly used for cold heading and cold extrusion of stainless steel parts; the standard covers wires, wire rods and bars of 0.8 to 100 mm (clause 1.1, table 14).
BS 970 (Part 1) 410S21 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 2) X12Cr13 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 410S21 vs IS 11169 (Part 2) X12Cr13 is a 94.9% 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 94.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
