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 J404:2000) 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 chemistry-only alloy steel grade; see the composition notes for product scope.
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.
