Strong Match — 91.8% match
based on chemical composition and mechanical property overlap.
IS 4367 16Ni8Cr6Mo2 (IS 4367:1991) and BS 970 (Part 3) 822M17 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Alloy Steel category.
IS 4367 16Ni8Cr6Mo2 is typically used for gears, camshafts, piston pins, splined shafts, aerospace and automotive case-hardened components., while BS 970 (Part 3) 822M17 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy case hardening steel (table 15).
IS 4367 16Ni8Cr6Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 822M17 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 4367 16Ni8Cr6Mo2 vs BS 970 (Part 3) 822M17 is a 91.8% 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 91.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
