ASTM A554 square tube

ASTM A554 stainless steel mechanical tube meets specified standards. The ASTM A554 tube has an excellent chemical composition of carbon, manganese, phosphorus, sulphur, silicon, chromium, and nickel. These tubes are more resistant to corrosive and oxidative conditions due to the composition. The mechanical qualities of SA554 Stainless Steel Tubing are outstanding. These tubes can be lengthened by 35% in the system and have a minimum tensile strength of 75ksi and a minimum yield strength of 30ksi. The tubes might be square or rectangular in shape. The ASME SA554 SS Square Tubing is passed through dies before being welded in place. This tubing can also be manufactured in seamless versions.

A554 Grade Mt 316L Rectangular Tube has moderate strength with excellent cold formability and weldability.

This tubing can also be manufactured in seamless versions. They are intended for usage in high-temperature and high-pressure environments. SA554 SS Rectangular Tubes feature increased stability and uneven rectangular cross sections. These tubes are extremely robust and are available in a variety of diameters to satisfy product specifications. ASTM A554 Ornamental Tubes is a gleaming and aesthetically pleasing quality with exceptional strength and durability. These tubes are an excellent replacement for traditional products in a variety of applications. They are a prevalent feature of steel grades 304 and 316.

The ASTM A554 Welded Mechanical Tubing is a tough grade made by flat-rolling steel and welding it in place with an automated welding technique. These tubes do not require any filler material to be welded in place. We maintain various sizes of tubes in stock, which can be purchased at any of our locations. Our supply chain enables us to deliver things to your door in a timely manner. For additional information on these products or their pricing, please contact us or visit any of our locations.
