Close Alternative — 81.2% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS890L (JIS G4305:2012) and ASTM A240/A240M N08904 (ASTM A240/A240M:2025) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS890L is typically used for cold-rolled stainless steel plates, sheet and strip, while ASTM A240/A240M N08904 is commonly used for pressure vessels and general applications (plate, sheet and strip).
JIS G4305 SUS890L is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A240/A240M N08904 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4305 SUS890L vs ASTM A240/A240M N08904 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.
