Close Alternative — 82.4% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20Cr4 (IS 11169 (Part 1):2022) and EN 10084 20MnCrS5 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 20Cr4 is typically 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), while EN 10084 20MnCrS5 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
IS 11169 (Part 1) 20Cr4 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 20MnCrS5 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 11169 (Part 1) 20Cr4 vs EN 10084 20MnCrS5 is a 82.4% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
