347 Stainless Steel Tube Price

How tubing is different from Pipe?

  • 347 Stainless Steel Tube is available in many different types of materials and wall thicknesses, and sizes actually make sense.
  • Tubing is sized by the outside diameter or O.D. 1" tubing actually measures 1" on the outside diameter (within a few thousands of an inch.) Tubing wall thicknesses are measured in gauges up to a point then convert to fractions of an inch, some wall thicknesses are even measured in millimeters.
  • Outside diameters range from 1/8" and beyond 12". Wall thicknesses range between 20 gauge (.035") and 2" thick.
  • Tubing is available in many types of materials, some including: stainless steel, steel alloys (4130), aluminum (6061, 6063, 2011, 3003, with various heat treating), inconel, monel, hastelloy, and more.
  • Tubing is also available in many types of drawing and forming processes some including: (cold drawn seamless, buttweld, electrical resistance welded ERW, drawn over mandrel DOM, hot finished seamless) and others.

Stainless Steel 347 is similar type of austentic steel as SS 304 with addition of columbium to its chemical properties. This addition to this high steel alloy stabilizes the steel and helps eliminating carbide precipitation. It has higher rupture and creep stress properties. This high steel alloy also has good mechanical properties that are advantageous for high temperature  service and excellent resistance to intergranular corrosion. SS 347 cannot be hardened through heat treatment, though elevated properties  can be attained through cold works.

Stainless Steel 347H is a higher carbon content version of SS 347.
