Related Material — 67.5% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 40Cr4 (IS 11169 (Part 1):2022) and SAE J404 50B46 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 40Cr4 is typically used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c), while SAE J404 50B46 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope.
IS 11169 (Part 1) 40Cr4 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 50B46 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 40Cr4 vs SAE J404 50B46 is a 67.5% 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 67.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
