AISI 302 Characteristics

  • Classic 18/8 composition providing proven general corrosion resistance in food & atmosphere
  • Higher carbon content yielding slightly greater strength than 304 in cold drawn condition
  • Completely non-magnetic in annealed condition with excellent cryogenic toughness
  • Great formability for cold-heading rivets, screws, and threaded rod manufacturing
  • Cost-effective stainless bolting alloy for sanitary and commercial applications

AISI 302 Applications

  • Food and beverage processing equipment bolting and sanitary fittings
  • Commercial kitchen hardware, architectural fasteners, and decorative panel studs
  • Springs, wire forms, screen mesh fasteners, and light structural hardware
  • Automotive trim fasteners, stamping clips, and non-corrosive bracket bolting
  • Appliance assemblies, bottling plant conveyors, and pump housing fasteners
