CSA G40.21 350A vs IS 11169 (Part 1) 10C4

CSA G40.21 350A (CSA G40.21-13 (R2023)) and IS 11169 (Part 1) 10C4 (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) 10C4 is classified under Carbon 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) 10C4 is commonly used for cold heading and cold extrusion of parts not heat treated after cold forming; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex a). CSA G40.21 350A is defined under Canadian Standards Association (CSA), originating from Canada, while IS 11169 (Part 1) 10C4 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, CSA G40.21 350A vs IS 11169 (Part 1) 10C4 is a 65.7% 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%.
