EN 10083-1 34CrNiMo6 vs IS 11169 (Part 1) 10Ni5Cr4
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-1 34CrNiMo6 (EN 10083-1:1991) and IS 11169 (Part 1) 10Ni5Cr4 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-1 34CrNiMo6 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), 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).
EN 10083-1 34CrNiMo6 is defined under European Standard (EN), originating from Europe, while IS 11169 (Part 1) 10Ni5Cr4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10083-1 34CrNiMo6 vs IS 11169 (Part 1) 10Ni5Cr4 is a 60.9% match.
As per mechanical properties, the match is 0%.
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.
