CSA G40.21 480A vs IS 11169 (Part 1) 26C10BT

CSA G40.21 480A (CSA G40.21-13 (R2023)) and IS 11169 (Part 1) 26C10BT (IS 11169 (Part 1):2022) are both steel grades. CSA G40.21 480A is classified under Structural Steel (Corten / Weathering), while IS 11169 (Part 1) 26C10BT is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. CSA G40.21 480A is typically used for high-strength atmospheric corrosion-resistant (weathering) structural steel; heavy exposed structural members, bridge girders, while IS 11169 (Part 1) 26C10BT is commonly used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c). CSA G40.21 480A is defined under Canadian Standards Association (CSA), originating from Canada, while IS 11169 (Part 1) 26C10BT is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, CSA G40.21 480A vs IS 11169 (Part 1) 26C10BT is a 63.8% 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 63.8%.
