Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 12Cr4Mo2 (IS 11169 (Part 1):2022) and SAE J404 4140 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 12Cr4Mo2 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 J404 4140 is commonly used for gears, shafts, dies, bolts, crankshafts.
IS 11169 (Part 1) 12Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 4140 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 12Cr4Mo2 vs SAE J404 4140 is a 76.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
