Product Detail

SS 304 tubing is a stainless steel tube made for different applications. There are different grades within the stainless tubes.

The Stainless Steel 304 tube is one of the most widely used because of the low cost. The ASTM A554 TP304 tube has certain level of corrosion resistance with good strength. The cost effectiveness of the alloy 304 tube make it adopted over a wide range of applications. The ASTM A270 TP304 tube has chromium and nickel components in the composition and it comes in different types such as the SS 304 seamless tubing and the electric resistance welded tubing.
