Stainless Steel Mechanical Tubing

SS 316 Dom Tubes Supplier in India

Stainless Steel Mechanical Tube is primarily utilised in mechanical and low gauge structural applications. Torsion and higher strength are provided by the Stainless Mechanical Tubing on the system. They are manufactured to varied standards and specifications to meet the requirements of diverse applications. Square Mechanical Tubing has improved corrosion resistance and is available in both seamless and welded versions. When compared to other standard pipes, Metric Mechanical Tubing offers more homogeneous qualities across the length of the tubes.

Both ASTM A511 and A511M specifications address Seamless Mechanical Tubing and applications. These Stainless Steel Hollow Bars are utilised in applications that demand high temperature strength and corrosion resistance. Heavy Wall Mechanical Tubing, both seamless cold-finished and seamless hot-finished, is the primary focus of the standards. The size, form, and other dimensions of the 304 Stainless Seamless Mechanical Tubing solutions can be tailored to meet the needs of the specific application.

The key benefit of SS Cold Drawn Mechanical Tubing is that it has a fast forming speed with a high yield without creating any coating damage. These cold drawn Stainless Steel Hollow Tubes can be cut into various brittle cross-sections to satisfy the needs of the specific application. They also have a high degree of plastic deformation, which boosts steel yield. The 316 Stainless Steel Mechanical Tubing is suited for a variety of industries such as chemical processing, automotive, food processing, power generation, and so on. In other words, mechanical tubes are an excellent choice for applications demanding precise tolerances and a high level of polish.
