CSA G40.21 260WT vs IS 11169 (Part 1) 16Ni4Cr3

CSA G40.21 260WT (CSA G40.21-13 (R2023)) and IS 11169 (Part 1) 16Ni4Cr3 (IS 11169 (Part 1):2022) are both steel grades. CSA G40.21 260WT is classified under Structural Steel (Corten / Weathering), while IS 11169 (Part 1) 16Ni4Cr3 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. CSA G40.21 260WT is typically used for weldable structural steel with guaranteed charpy v-notch low-temperature toughness; secondary members, stair stringers, bracing in cold-climate service, while IS 11169 (Part 1) 16Ni4Cr3 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 260WT is defined under Canadian Standards Association (CSA), originating from Canada, while IS 11169 (Part 1) 16Ni4Cr3 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, CSA G40.21 260WT vs IS 11169 (Part 1) 16Ni4Cr3 is a 66.6% 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%.
