Advanced stainless steel materials are often used for critical applications and their metallurgical nature makes these tubes more complex to bend. Due to this bending complexity, engineering designers sometimes select a basic steel grade that fabricators know how to bend. Consequently, they will not benefit from the obvious advantages of a more advanced stainless steel. With our tube bending support, you will not have to make such a choice.

What makes stainless steel tubes difficult to bend?

Advanced stainless steels typically have higher strength and work hardening rates than common stainless steels. Bending can therefore lead to material failure, ovalization, wall thinning, creasing and cracks, if not performed correctly.

Sandvik's tube bending support utilizes advanced material models based on extensive test data. Throughout decennials of stainless steel development, we have tested thousands of samples, assessed and stored data. This data is the basis for our bending simulation, using a specially developed finite element model. A group of Sandvik simulation experts calculates the optimum parameters for bending each specific alloy, tube size and shape. The simulation can also use specific bending machine parameters such as bending tool and forces.

When to use tube-bending support

There are several occasions when tube bending support is beneficial:

  • When you are upgrading your equipment with high performance stainless steel tubes and want to know if it is possible to fabricate the same shape as your existing equipment
  • When engineering new designs and you want to know the minimum radius possible with a certain stainless grade and tube size
  • If you are a fabricator and want to know if it is possible to quote a certain bending shape in a complex stainless steel grade
  • When you need to know which tool geometry, force, speed and temperature that should be used for the best bending result
