AISI 420 Stainless Steel Foil

Formula: Fe 86.7/Cr 13.0/C 0.3
Form: Foil/Film/Sheet
Material: AISI 420 Stainless Steel
Commodity: Alloys
AISI 420 Stainless Steel Foils are made of a martensitic stainless steel that provides high strength and good corrosion resistance. With 43 variations available, their hardness makes them suitable for applications like surgical tools and valve components. These alloy foils can also be used in the chemical and food processing industries where corrosion resistance is needed. With a range of customization options, Goodfellow’s AISI 420 foils can be tailored to meet specific requirements.
