Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
SAE J404 4820 (SAE J404:2000) and IS 11169 (Part 1) 20Ni7Mo2 (IS 11169 (Part 1):1984) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 4820 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while IS 11169 (Part 1) 20Ni7Mo2 is commonly used for cold heading and cold extrusion; the standard covers wires, wire rods and bars of 2 to 100 mm diameter (clause 1.1).
SAE J404 4820 is defined under SAE International, originating from United States, while IS 11169 (Part 1) 20Ni7Mo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, SAE J404 4820 vs IS 11169 (Part 1) 20Ni7Mo2 is a 84.6% 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%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
