ISO 683-17 20NiCrMo7 vs IS 11169 (Part 1) 20Ni2Cr2Mo3

Close Alternative — 78.6% match based on chemical composition and mechanical property overlap.

ISO 683-17 20NiCrMo7 (ISO 683-17:1999) and IS 11169 (Part 1) 20Ni2Cr2Mo3 (IS 11169 (Part 1):2022) are both steel grades. Both fall under the Alloy Steel category. ISO 683-17 20NiCrMo7 is typically used for used in large gears, turbine shafts, marine gearboxes, heavy-duty pinions, and industrial transmissions., while IS 11169 (Part 1) 20Ni2Cr2Mo3 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). ISO 683-17 20NiCrMo7 is defined under International Organization for Standardization (ISO), originating from International, while IS 11169 (Part 1) 20Ni2Cr2Mo3 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, ISO 683-17 20NiCrMo7 vs IS 11169 (Part 1) 20Ni2Cr2Mo3 is a 78.6% 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 78.6%.
