IS 11169 (Part 1) 45C8 vs SAE J403 1042

Strong Match — 91.7% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 45C8 (IS 11169 (Part 1):1984) and SAE J403 1042 (SAE J403:2014) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 45C8 is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1), while SAE J403 1042 is commonly used for chemistry-only grade; product scope as listed in the composition notes. IS 11169 (Part 1) 45C8 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J403 1042 is defined under SAE International, originating from United States.

As per chemical composition, IS 11169 (Part 1) 45C8 vs SAE J403 1042 is a 91.7% 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 91.7%.
