Close Alternative — 82.3% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 16Cr4 (IS 11169 (Part 1):2022) and SAE J404 5115 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 16Cr4 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 5115 is commonly used for case hardened gears, cams, shafts.
IS 11169 (Part 1) 16Cr4 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5115 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 16Cr4 vs SAE J404 5115 is a 82.3% 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 82.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
