Strong Match — 89.1% match
based on chemical composition and mechanical property overlap.
SAE J404 5130 (SAE J404:2000) and GB/T 3077 30Cr (GB/T 3077:2015) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 5130 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while GB/T 3077 30Cr is commonly used for hot-rolled or forged structural alloy steel bars.
SAE J404 5130 is defined under SAE International, originating from United States, while GB/T 3077 30Cr is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, SAE J404 5130 vs GB/T 3077 30Cr is a 89.1% 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 89.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
