Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
JIS G4305 SUS440A (JIS G4305:2012) and ASTM A959 S42010 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4305 SUS440A is typically used for cold-rolled stainless steel plates, sheet and strip, while ASTM A959 S42010 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
JIS G4305 SUS440A is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 S42010 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4305 SUS440A vs ASTM A959 S42010 is a 72.5% 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 69.9%.
