BS 970 (Part 1) 170H41 vs IS 11169 (Part 1) 10Ni5Cr4
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 170H41 (BS 970 (Part 1):1991) and IS 11169 (Part 1) 10Ni5Cr4 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 170H41 is typically used for through hardening boron steel (section three), while IS 11169 (Part 1) 10Ni5Cr4 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) 170H41 is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 10Ni5Cr4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 (Part 1) 170H41 vs IS 11169 (Part 1) 10Ni5Cr4 is a 54.6% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
