Strong Match — 86.1% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C4GC (IS 11169 (Part 1):2022) and EN 10084 C15E (EN 10084:2008) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 20C4GC 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 C15E is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
IS 11169 (Part 1) 20C4GC is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 C15E is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 11169 (Part 1) 20C4GC vs EN 10084 C15E is a 86.1% 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 86.1%.
Frequently Compared With IS 11169 (Part 1) 20C4GC:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
