Close Alternative — 84.6% match
based on chemical composition and mechanical property overlap.
GB/T 3077 35Cr (GB/T 3077:2015) and SAE J404 5132 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
GB/T 3077 35Cr is typically used for hot-rolled or forged structural alloy steel bars, while SAE J404 5132 is commonly used for high-tensile bolts, studs, shafts and engineering components requiring surface hardness.
GB/T 3077 35Cr is defined under Guobiao Standards (GB/T), originating from China, while SAE J404 5132 is defined under SAE International, originating from United States.
As per chemical composition, GB/T 3077 35Cr vs SAE J404 5132 is a 84.6% 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 84.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
