Related Material — 67.3% match
based on chemical composition and mechanical property overlap.
EN 10083-2 C45 (EN 10083-2:2006) and IS 11169 (Part 1) 40C15 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-2 C45 is typically used for shafts, gears, bolts, machine parts, tools, 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 10083-2 C45 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 10083-2 C45 vs IS 11169 (Part 1) 40C15 is a 67.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 67.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
