Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
SAE J404 4135 (SAE J404:2000) and IS 11169 (Part 1) 12Cr4Mo2 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 4135 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while IS 11169 (Part 1) 12Cr4Mo2 is commonly 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).
SAE J404 4135 is defined under SAE International, originating from United States, while IS 11169 (Part 1) 12Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, SAE J404 4135 vs IS 11169 (Part 1) 12Cr4Mo2 is a 78.1% 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.
