IS 11169 (Part 1) 15C4GC (case hardening) vs EN 10084 C15R

Strong Match — 90.1% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 15C4GC (case hardening) (IS 11169 (Part 1):2022) and EN 10084 C15R (EN 10084:2008) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 15C4GC (case hardening) 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 C15R is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1). IS 11169 (Part 1) 15C4GC (case hardening) is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 C15R is defined under European Standard (EN), originating from Europe.

As per chemical composition, IS 11169 (Part 1) 15C4GC (case hardening) vs EN 10084 C15R is a 90.1% 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 90.1%.
