Improving material performance with surface hardening

Mia Grundtvig (Expanite) explains how surface hardening can solve roughness and insufficient hardness of stainless steel screws

Galling is serious…but there are solutions

Galling is a form of wear that is caused by metal surfaces in gliding contact with one other, such as the potentially hundreds of stainless steel bolts and fasteners holding production equipment and its moving parts together. With potentially disastrous effects resulting from galled fasteners seizing or even being subject to a fatigue breakage, industry players are advised to counter this threat.
