Close Alternative — 73.6% match
based on chemical composition and mechanical property overlap.
EN 10083-1 2C40 (EN 10083-1:1991) and IS 11169 (Part 1) 40C15 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-1 2C40 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), while IS 11169 (Part 1) 40C15 is commonly used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c).
EN 10083-1 2C40 is defined under European Standard (EN), originating from Europe, while IS 11169 (Part 1) 40C15 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10083-1 2C40 vs IS 11169 (Part 1) 40C15 is a 73.6% 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 73.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
