Salzgitter Mannesmann Stainless Tubes.

Salzgitter Mannesmann Stainless Tubes is one of the worldwide leading manufacturers of seamless stainless steel and nickel based alloy tubes and pipes.

Our company has one of the largest product portfolios in this sector and a 125 years long history that dates back to invention of the seamless stainless steel tube.


The more things change…

The industrial production of steel tubes dates back to the ground-breaking invention of the Mannesmann Brothers in the late 19th century. Just a short while later Mannesmann became known and respected for its quality throughout the world.

Today, in the 21st century, the future is about to be changed once more – by the CERN particle accelerator.

We equipped this world-renowned project with stainless steel and nickel alloy tubes, which remain the industry benchmark.
