Close Alternative — 82% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS301L (JIS G4304:2021) and ASTM A240/A240M S30153 (ASTM A240/A240M:2025) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS301L is typically used for hot-rolled stainless steel plates and strips, while ASTM A240/A240M S30153 is commonly used for pressure vessels and general applications (plate, sheet and strip).
JIS G4304 SUS301L is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A240/A240M S30153 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4304 SUS301L vs ASTM A240/A240M S30153 is a 98.1% match.
As per mechanical properties, the match is 50%.
Combined, this makes them a close alternative overall at 82%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
