309

309 Stainless Steel Square Pipes are composed of iron, chromium, and nickel. The chromium content of 309 stainless steel gives it excellent corrosion resistance, while the nickel adds strength, ductility, and enhanced formability. Iron is also a key component in the alloy structure, providing added strength and durability. This type of steel has an attractive appearance thanks to its high polishability and bright finish.

309 SS Square Pipes offer excellent corrosion resistance, making them suitable for use in coastal and offshore environments and any applications requiring precision fabrication or machining. They are also ideal for structural components such as screws and bolts due to their strength and ductility. In addition to these uses, this type of steel has an attractive appearance thanks to its high polishability and bright finish, making it ideal for decorative applications. The alloy is also non-magnetic and highly resistant to oxidation, even at very high temperatures.

The equivalent materials for stainless steel 309 square pipes include: DIN 1.4828, ASTM A213, ASTM A249, ASTM A312, ASTM A358, ASTM A409, ASTM A511. These materials are equivalent to stainless steel 309 in terms of chemical composition and mechanical properties and can be used interchangeably in most applications.

Stainless steel 309 square pipes are available in a range of sizes to suit a variety of applications. The size of a square pipe is generally referred to as its nominal bore (NB) and is expressed in millimetres (mm). Some common sizes of stainless steel 309 square pipes include:


  • 15mm x 15mm
  • 20mm x 20mm
  • 25mm x 25mm
  • 30mm x 30mm
  • 40mm x 40mm
  • 50mm x 50mm
  • 60mm x 60mm
  • 80mm x 80mm
  • 100mm x 100mm


It's important to note that the actual dimensions of the pipe may be slightly different from the nominal bore size, as the wall thickness of the pipe will also impact the overall size.
