Related Material — 68.3% match
based on chemical composition and mechanical property overlap.
JIS G4303 SUS304 (JIS G4303:2021) and ASTM A959 .- (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4303 SUS304 is typically used for food equipment, chemical vessels, architectural applications, while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
JIS G4303 SUS304 is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 .- is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4303 SUS304 vs ASTM A959 .- is a 68.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 68.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
