Strong Match — 88.5% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M S32506 (ASTM A240/A240M:2025) and JIS G4305 SUS329J4L (JIS G4305:2012) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M S32506 is typically used for pressure vessels and general applications (plate, sheet and strip), while JIS G4305 SUS329J4L is commonly used for cold-rolled stainless steel plates, sheet and strip.
ASTM A240/A240M S32506 is defined under ASTM International, originating from United States, while JIS G4305 SUS329J4L is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A240/A240M S32506 vs JIS G4305 SUS329J4L is a 82.7% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 88.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
