Close Alternative — 82.2% match
based on chemical composition and mechanical property overlap.
ASTM A959 317LM (ASTM A959:2011) and JIS G4305 SUS317LN (JIS G4305:2012) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 317LM is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4305 SUS317LN is commonly used for cold-rolled stainless steel plates, sheet and strip.
ASTM A959 317LM is defined under ASTM International, originating from United States, while JIS G4305 SUS317LN is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A959 317LM vs JIS G4305 SUS317LN is a 82.2% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
