IS 11169 (Part 1) 4C2 vs GB/T 699 25

Related Material — 69.9% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 1) 4C2 (IS 11169 (Part 1):2022) and GB/T 699 25 (GB/T 699:2015) are both steel grades. Both fall under the Carbon Steel category. IS 11169 (Part 1) 4C2 is typically 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), while GB/T 699 25 is commonly used for hot-rolled or forged quality carbon structural steel bars up to 250 mm. IS 11169 (Part 1) 4C2 is defined under Bureau of Indian Standards (IS), originating from India, while GB/T 699 25 is defined under Guobiao Standards (GB/T), originating from China.

As per chemical composition, IS 11169 (Part 1) 4C2 vs GB/T 699 25 is a 71.1% 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 69.9%.
