EN 10084 C15E vs IS 11169 (Part 1) 15C4GC (case hardening)
Strong Match — 91.8% match
based on chemical composition and mechanical property overlap.
EN 10084 C15E (EN 10084:2008) and IS 11169 (Part 1) 15C4GC (case hardening) (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Carbon Steel category.
EN 10084 C15E is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while IS 11169 (Part 1) 15C4GC (case hardening) 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 C15E is defined under European Standard (EN), originating from Europe, while IS 11169 (Part 1) 15C4GC (case hardening) is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10084 C15E vs IS 11169 (Part 1) 15C4GC (case hardening) is a 91.8% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 91.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
