Lengths are cut to a precision of +/- 2mm (0.078 inches).

Outer diameter dimensional tolerance +/- 1% (but usually better than this)

Other diameters, Material and bars lengths are available - Please ask.


This material is brilliant for milling, turning and drilling purposes and perfect for the model engineer and machinist.

To ensure the item arrives to you in the best possible condition, these rods are dispatched attached to a stiffener to prevent bending during shipping.

General Properties

Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. Alloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion resistant properties. Due to the presence of sulphur in the steel composition, Alloy 303 is the most readily machinable austenitic stainless steel; however, the sulphur addition does lower Alloy 303’s corrosion resistance to below that of Alloy 304. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulphur does reduce this a little as well.

Applications

Alloy 303 is frequently used in applications that require parts to be heavily machined. Some examples include:

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