IS 11169 (Part 1) 15C4GC (case hardening) vs SAE J403 1015

Strong Match — 88.4% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 15C4GC (case hardening) (IS 11169 (Part 1):2022) and SAE J403 1015 (SAE J403:2014) 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 SAE J403 1015 is commonly used for chemistry-only grade; product scope as listed in the composition notes. IS 11169 (Part 1) 15C4GC (case hardening) is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1015 is defined under SAE International, originating from United States.

As per chemical composition, IS 11169 (Part 1) 15C4GC (case hardening) vs SAE J403 1015 is a 88.4% 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 88.4%.
