AISI 303/303F Stainless Steel Bar

Key Features

• Superior Machinability
  AISI 303/303F is one of the easiest stainless steels to machine, thanks to the high sulfur content in 303F, which enhances its cutting ability and allows for faster tool speeds.
• Corrosion Resistance
  Excellent resistance to corrosion in a wide range of environments, including mild acids, fresh water, and atmospheric conditions.
• Non-Magnetic Properties
  AISI 303/303F stainless steel bars retain non-magnetic characteristics in annealed conditions, making them suitable for applications where magnetic properties are a concern.
• Toughness and Durability
  AISI 303 offers a great balance of strength and toughness, providing reliable performance even under stressful operating conditions.
• Formability
  While both 303 and 303F can be easily cold-worked, AISI 303 is more commonly used for parts requiring high strength, while 303F is ideal for parts requiring extensive machining.
