A Decisive Innovation!

GTS 12 – The steel innovation from Alfred Giesser.
Developed in scientific cooperation with Ruhr University Bochum.

 

The Steel that
Defies the Elements

The higher the electrical breakdown potential of a
steel, the greater its corrosion resistance.
GTS 12 has considerably enhanced physical
properties. And its breakdown potential is also far
above that of conventional steels. This results in
significantly greater corrosion resistance.

Hardness is a Science
in and of Itself 

In close collaboration with the scientists at the Ruhr University Bochum, the alloy composition has been successfully optimised. The addition of nitrogen (N) makes it possible. As a result, GTS 12 is harder than all comparable stainless steels.

Hard Times for
PM Steel

Up until now, PM steel was the benchmark when it came to corrosion resistance, hardness and toughness. PM steel is often excluded from consideration for many applications due to its high material costs. GTS 12 offers benefits and properties similar to those of PM steel. And it’s available at a small fraction of the cost!

GTS 12 – This Steel is 
the Hard One

Abrasion, wear, rust, aggressive cleaning agents – steel has many enemies! GTS 12 offers all of the properties necessary to provide effective resistance against them. That makes it the ideal material in the particularly critical environments of the food and pharmaceutical industries as well as in machinery construction.
