GB/T 3077 35Cr2Ni4Mo vs IS 11169 (Part 1) 35Cr4Mo2
Related Material — 65.4% match
based on chemical composition and mechanical property overlap.
GB/T 3077 35Cr2Ni4Mo (GB/T 3077:2015) and IS 11169 (Part 1) 35Cr4Mo2 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
GB/T 3077 35Cr2Ni4Mo is typically used for hot-rolled or forged structural alloy steel bars, while IS 11169 (Part 1) 35Cr4Mo2 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).
GB/T 3077 35Cr2Ni4Mo is defined under Guobiao Standards (GB/T), originating from China, while IS 11169 (Part 1) 35Cr4Mo2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, GB/T 3077 35Cr2Ni4Mo vs IS 11169 (Part 1) 35Cr4Mo2 is a 65.4% 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 65.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
