Our high-strength stainless steel products offer not only higher strength with lighter structures but also exceptional elongation properties as well as corrosion and fire resistance. STALA high-strength classes offer sustainable choice in every purpose. In addition to remarkable sustainability benefits, high-strength stainless steel saves you costs and offers strength and safety that the more traditional material choices won’t get you.

High-strength stainless steel tubes

High-strength stainless steel offers not only superior strength but also high elongation and fire- and corrosion resistance. We offer stainless steel tubes with high-strength classes in the following Austenitic, Ferritic, and Lean Duplex material grades.

Significant weight savings

Due to high-strength stainless steel’s mechanical properties, you can have even up to 50 % thinner tube wall thickness without compromising the structure’s functionality, stability, or safety. The high-strength stainless steel hollow section will maintain the same outer dimension and bending resistance as standard materials.

Weight saving also equals less material which results in a smaller carbon footprint. Lighter structural weight also decreases the carbon footprint of transportation.

Save material, gain cost savings

Lighter and stronger structures come with many advantages also when it comes to costs. High-strength stainless steel is made to last forever and its mechanical properties make it also maintenance-free. It is 100 % recyclable so nothing is wasted. These factors alone produce cost savings during the product’s long life cycle.

In addition, the transportation and installation phase for lighter structures costs less. High-strength stainless steel is highly corrosion and fire-resistant and it doesn’t need any time-consuming coating phase that means more costs to the final product.

This makes high-strength stainless steel also a more sustainable choice; it doesn’t need any toxic paints that harm the environment.

Material that is hard to beat

High-strength stainless steel is made to last rough conditions and load-bearing structures. It has unique elongation properties. It has a higher yield and tensile strength and better abrasion resistance than traditional stainless steel grades or structural steel. While offering undeniable strength in applications high-strength stainless steel can also be combined with other steel grades.

You can use the same methods, welding wires, and gases with austenitic high-strength stainless steel as you would with traditional austenitic grades.

High-strength choices for every need

High-strength materials are a versatile choice. They can be used in applications such as

  • architectural applications like glass walls and balconies
  • civil engineering applications such as dam structures
  • process and transport tanks
  • cable supporting structures
  • bridges
  • process equipment due to better abrasion resistance
  • vehicle bodies and chassis
  • other load-bearing applications
