Stainless Steel 304L Seamless Pipe

Stainless Steel DIN 1.4307 Welded Pipe, View Dimensions of 304L SS Hexagonal Pipe, SS UNS S30403 Pipes Sizes

The Stainless Steel 304L Seamless Pipe is made from a single piece of material, giving it a smoother finish. It has a minimum yield strength of 205 MPa and a minimum tensile strength of 515 MPa, making it strong enough for high-pressure applications. However, its corrosion resistance is lower. On the other hand, the Stainless Steel 304L Welded Pipe can handle high temperatures, making it suitable for applications up to 870°C.

The ASTM A312 TP304L ERW Pipe is made from 304 grade austenitic stainless steel. It is used in high-pressure and high-temperature applications, like boilers, heat exchangers, and condensers. The pipes come in various sizes and standards, such as the ANSI B16.5 and DIN 1.4307, ranging from ½ inch to 24 inches for seamless and welded pipes, and up to 100 inches for electric fusion welded pipes. For more details or pricing information on the SS UNS S30403 Pipe, feel free to contact us.
