This article is a Q & A with Rune Strand regarding ExpaniteHard-Ti. Strand is project manager and material scientist at Expanite A/S, and he holds an MSc in material science and manufacturing. He has spent most of his career in the field of surface hardening and heat treatment of stainless steel.

We continue our discussion of the heat treatment of fasteners.

The need for lighter and safer vehicles increases the demand for stronger steels in automotive bodies. Aerospace components have many of the same demands but on a more rigidly controlled level with a wider variety of materials.
