Strong Match — 86.9% match
based on chemical composition and mechanical property overlap.
GB/T 3077 35CrMo (GB/T 3077:2015) and SAE J404 4135 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
GB/T 3077 35CrMo is typically used for used for connecting rods, gears, shafts, bolts, spindles, and pressure vessel parts., while SAE J404 4135 is commonly used for gears, shafts, pressure vessels, high tensile bolts.
GB/T 3077 35CrMo is defined under Guobiao Standards (GB/T), originating from China, while SAE J404 4135 is defined under SAE International, originating from United States.
As per chemical composition, GB/T 3077 35CrMo vs SAE J404 4135 is a 86.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 86.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
