Strong Match — 96% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20Ni7Mo2 (IS 11169 (Part 1):1984) and SAE J404 4620 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 20Ni7Mo2 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 4620 is commonly used for used for gears, bearings, shafts, transmission parts, pinions, and heavy-duty carburized components..
IS 11169 (Part 1) 20Ni7Mo2 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 4620 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 20Ni7Mo2 vs SAE J404 4620 is a 96% 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 96%.
