Related Material — 55% match
based on chemical composition and mechanical property overlap.
GB/T 3077 35Cr2Ni4Mo (GB/T 3077:2015) and IS 1570 (Part 4) 07Cr4Mo6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
GB/T 3077 35Cr2Ni4Mo is defined under Guobiao Standards (GB/T), originating from China, while IS 1570 (Part 4) 07Cr4Mo6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, GB/T 3077 35Cr2Ni4Mo vs IS 1570 (Part 4) 07Cr4Mo6 is a 55% 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 55%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
