Strong Match — 96.8% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS410 (JIS G4304:2021) and JIS G4305 SUS403 (JIS G4305:2012) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS410 is typically used for hot-rolled stainless steel plates and strips, while JIS G4305 SUS403 is commonly used for cold-rolled stainless steel plates, sheet and strip.
JIS G4304 SUS410 is defined under Japanese Industrial Standards (JIS), originating from Japan, while JIS G4305 SUS403 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, JIS G4304 SUS410 vs JIS G4305 SUS403 is a 95.1% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 96.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
