BS 970 (Part 1) 822M17 vs IS 11169 (Part 1) 16Ni8Cr6Mo2
Strong Match — 86% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 822M17 (BS 970 (Part 1):1983) and IS 11169 (Part 1) 16Ni8Cr6Mo2 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 822M17 is typically used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties)., while IS 11169 (Part 1) 16Ni8Cr6Mo2 is commonly used for cold heading and cold extrusion of parts that are case hardened; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex b).
BS 970 (Part 1) 822M17 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 16Ni8Cr6Mo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 822M17 vs IS 11169 (Part 1) 16Ni8Cr6Mo2 is a 86% 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 86%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
