CSA G40.21 50W vs IS 11169 (Part 1) 16Ni3Cr2

Related Material — 65% match based on chemical composition and mechanical property overlap.

CSA G40.21 50W (CSA G40.21-13 (R2023)) and IS 11169 (Part 1) 16Ni3Cr2 (IS 11169 (Part 1):2022) are both steel grades. CSA G40.21 50W is classified under Structural Steel (Corten / Weathering), while IS 11169 (Part 1) 16Ni3Cr2 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. CSA G40.21 50W is typically used for bridges, architectural structures, transmission towers, outdoor exposed structures, railway wagons., while IS 11169 (Part 1) 16Ni3Cr2 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). CSA G40.21 50W is defined under Canadian Standards Association (CSA), originating from Canada, while IS 11169 (Part 1) 16Ni3Cr2 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, CSA G40.21 50W vs IS 11169 (Part 1) 16Ni3Cr2 is a 70.5% 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 65%.
