What is stainless steel mechanical tube?

A Mechanical Tube is mainly used in different mechanical and light gauge structural applications. The Stainless Steel Mechanical Tube comes with torsion and superior strength. They are produced for meeting different end use requirements, standards, tolerances and specifications for varied services.

The Stainless Mechanical Tubing comes with enhanced corrosion resistance properties and available in both seamless and welded configurations. They have more uniformity in its properties throughout the length of the tubes compared to the other standard pipes. The mechanical tubes can be found in agricultural and dairy equipment.

Difference between astm a511 and a511m seamless mechanical tubing

Both the specifications ASTM A511 and A511M cover for Seamless Mechanical Tubing and applications. They are used for applications where high temperature strength and corrosion resistance are essential requirements. The specifications primarily cover seamless cold-finished and seamless hot-finished Square Mechanical Tubing.

The size, shape, and other dimensions of the tubing can be customized according to the specific application requirements. However, the difference is, ASTM is expressed in imperial units whereas A511M is Metric Mechanical Tubing. It is quite helpful for countries using metric system for measurements.

Advantages & uses of SS cold drawn mechanical tubing

The primary advantage of SS Cold Drawn Mechanical Tubing is that it offers high forming speed with a high yield without causing any damage to the coating. This cold drawn tube can be cut into different forms of brittle cross-section to meet the specific application needs. They also come with a great plastic deformation, which increases the yield of the steel. The 304 Stainless Seamless Mechanical Tubing need less energy in the production process and are affordable. They offer great accuracy during fabrication which can reduce the labor cost. The tubes have tighter tolerance and great surface finish.

The 316 Stainless Steel Mechanical Tubing can be ideally used in a wide range of applications which include chemical processing, automotive, food processing, power generation, etc. They are also found in heat exchangers and automotive sectors.

SS cold drawn mechanical tubing and Heavy wall mechanical tubing is delivered in random lengths or cut to fixed lengths
