Strong Match — 100% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS312L (JIS G4305:2012) and JIS G4304 SUS312L (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS312L is typically used for cold-rolled stainless steel plates, sheet and strip, while JIS G4304 SUS312L is commonly used for hot-rolled stainless steel plates and strips.
JIS G4305 SUS312L is defined under Japanese Industrial Standards (JIS), originating from Japan, while JIS G4304 SUS312L is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, JIS G4305 SUS312L vs JIS G4304 SUS312L is a 100% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
