Stainless Steel SS304, often referred to as 18/8 stainless steel due to its composition of 18% chromium and 8% nickel, is an austenitic stainless steel that is non-magnetic and highly resistant to corrosion. This makes it the perfect material for environments where exposure to moisture and aggressive chemicals is common. SS304 can withstand temperatures up to 870°C (1600°F) in intermittent service, providing excellent strength and resistance to oxidation. These characteristics make SS304 an essential material in various sectors, including food processing, pharmaceuticals, automotive, and architectural designs.

Heat Resistance:

  • Good oxidation resistance at temperatures up to 1700oF (927 oC)
  • Continuous use at temperatures above 1400oF (760oC) is not usually recommended due to carbide precipitation which can lead to irregular scaling
  • Does not have a low carbon content so it is also vulnerable to sensitization

Welding Characteristics:

  • Not generally recommended, but may be welded with some difficulty
  • May be welded with Alloy 310 electrodes
  • Should be annealed after welding to re-dissolve precipitated carbides

Machinability:

  • High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell
  • Will work harden; therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.

Applications:

  • Nuts and bolts
  • Aircraft fittings
  • Gears
  • Screws
  • Shafts
  • Electrical switchgear components
  • Bushings
