Close Alternative — 82.9% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20MnCr5 (IS 11169 (Part 1):1984) and SAE J404 5120 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 20MnCr5 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 J404 5120 is commonly used for case hardened gears, pins, shafts, cams, automotive transmission parts.
IS 11169 (Part 1) 20MnCr5 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5120 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 20MnCr5 vs SAE J404 5120 is a 82.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82.9%.
