based on chemical composition and mechanical property overlap.
EN 10084 18NiCr5-4 (EN 10084:2008) and IS 11169 (Part 1) 10Ni5Cr4 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 18NiCr5-4 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), 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 10084 18NiCr5-4 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 10084 18NiCr5-4 vs IS 11169 (Part 1) 10Ni5Cr4 is a 86.9% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a related material overall at 57.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
