Finnish stainless-steel producer Out- okumpu and Swedish fuel-tank-manu- facturer TechROi Fuel Systems (TFS) have developed a new stainless-steel fuel tank, being used in the new Saab 9-3 manu- factured by National Electric Vehicle Swe- den AB in Trollhättan, Sweden.

Parts built from EOS StainlessSteel 316L have a chemical composition cor- responding to ASTM F138. In the medical industry, this alloy finds use in surgical instruments, endoscopic surgery, ortho- pedics and implants. The material also is a good choice for use in the watch (see the accompanying photo of a watch case) and jewelry industries, where the design- er benefits from extensive freedom of design. And in the aerospace industry, EOS StainlessSteel is a good choice for the manufacture of clamping elements or heat exchangers.

New Saab Stainless- Steel Fuel Tank Pushes Plastic to the Curb
The new tank offers a competitive alternative to plastic tanks. It employs Outokumpu HyTens stainless steel, which allowed designers to specify extremely thin walls. As a result, the tank weighs approximately 3 kg lighter than a compa- rable plastic fuel tank. Further, the stain- less-steel tank provides excellent crash properties due to deformation hardening of the grade.
Says Outokumpu simulation and form- ing expert Ramin Moshfegh:
“The concept is a result of number of factors—good design, proper material
