GB/T 3077 15CrNiMo vs IS 11169 (Part 1) 17Ni2Cr2Mo2

Close Alternative — 72.4% match based on chemical composition and mechanical property overlap.

GB/T 3077 15CrNiMo (GB/T 3077:2015) and IS 11169 (Part 1) 17Ni2Cr2Mo2 (IS 11169 (Part 1):2022) are both steel grades. Both fall under the Alloy Steel category. GB/T 3077 15CrNiMo is typically used for hot-rolled or forged structural alloy steel bars, while IS 11169 (Part 1) 17Ni2Cr2Mo2 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). GB/T 3077 15CrNiMo is defined under Guobiao Standards (GB/T), originating from China, while IS 11169 (Part 1) 17Ni2Cr2Mo2 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, GB/T 3077 15CrNiMo vs IS 11169 (Part 1) 17Ni2Cr2Mo2 is a 72.4% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 72.4%.
