CSA G40.21 350A vs IS 11169 (Part 1) 16Ni3Cr2

CSA G40.21 350A (CSA G40.21-13 (R2023)) and IS 11169 (Part 1) 16Ni3Cr2 (IS 11169 (Part 1):2022) are both steel grades. CSA G40.21 350A 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 350A is typically used for exposed structural steelwork, bridges, retaining walls, coastal infrastructure, architectural facades., 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 350A 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 350A 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%.
