Close Alternative — 76.9% match
based on chemical composition and mechanical property overlap.
JIS G4303 SUS316 (JIS G4303:2021) and ASTM A959 316LHN (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4303 SUS316 is typically used for marine applications, chemical processing, pharmaceutical equipment, while ASTM A959 316LHN is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
JIS G4303 SUS316 is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 316LHN is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4303 SUS316 vs ASTM A959 316LHN is a 76.9% 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 76.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
