Helsinki-based Outokumpu says stainless steels are ideal for lightweight, safety-critical structural parts and have put it to use in the series production of EV battery enclosures
The use of stainless steel in the automotive industry has been typically limited to components in the exhaust line, but the corrosion-resistant metal demonstrates a number of properties that make it attractive for the manufacture of other parts, too.
Indeed, Ford produced a number of concept cars with stainless steel bodies from the 1930s through to the 1970s and, perhaps most famously, the DMC DeLorean featured stainless steel body panels mounted to its glass fibre-reinforced plastic monocoque. However, the wider adoption of stainless steel in such applications has been limited by a number of factors – principally its relatively high price.
