Close Alternative — 81.2% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M N08904 (ASTM A240/A240M:2025) and JIS G4304 SUS890L (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M N08904 is typically used for pressure vessels and general applications (plate, sheet and strip), while JIS G4304 SUS890L is commonly used for hot-rolled stainless steel plates and strips.
ASTM A240/A240M N08904 is defined under ASTM International, originating from United States, while JIS G4304 SUS890L is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A240/A240M N08904 vs JIS G4304 SUS890L is a 96.8% match.
As per mechanical properties, the match is 50%.
Combined, this makes them a close alternative overall at 81.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
