Minimal Match — 47.9% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS420J2 (JIS G4304:2021) and GB/T 3280 06Cr19Ni10 (GB/T 3280-2015) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS420J2 is typically used for hot-rolled stainless steel plates and strips, while GB/T 3280 06Cr19Ni10 is commonly used for used for kitchen equipment, food processing machinery, chemical tanks, piping, architectural panels, and fasteners..
JIS G4304 SUS420J2 is defined under Japanese Industrial Standards (JIS), originating from Japan, while GB/T 3280 06Cr19Ni10 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, JIS G4304 SUS420J2 vs GB/T 3280 06Cr19Ni10 is a 71.9% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 47.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
