AISI 420 Stainless Steel Disk

Formula: Fe 86.7/Cr 13.0/C 0.3

Form: Disk

Material: AISI 420 Stainless Steel

Commodity: Alloys

AISI 420 Stainless Steel disks are made from a high-carbon steel with good hardness and wear resistance properties. They also have moderate corrosion resistance and can be heat treated to achieve high strength. AISI 420 Stainless Steel disks have applications in cutlery, surgical instruments, valves, bearings, and other parts requiring hardness and corrosion resistance. With 100 variations available, Goodfellow's AISI 420 disks offer options for different dimensions, thicknesses and surface finishes to suit diverse applications.
