Close Alternative — 74% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 18Cr4Mo2S3 (IS 11169 (Part 1):2022) and SAE J404 4130 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 18Cr4Mo2S3 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 4130 is commonly used for aircraft structures, pressure vessels, high tensile tubes.
IS 11169 (Part 1) 18Cr4Mo2S3 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 4130 is defined under SAE International, originating from United States.
As per chemical composition, IS 11169 (Part 1) 18Cr4Mo2S3 vs SAE J404 4130 is a 74% 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 74%.
