FLEXIBLE FORMABILITY Flexibility is the cornerstone of modern vehicle design. Whether for visual appeal or mechanical necessity, stainless steel allows for intricate and complex geometries without compromising structural integrity. Its diverse grades have adjustable ductility and hardness, often eliminating the need for multiple materials in a single project. By optimising mechanical
properties through temper rolling and strain hardening, a single stainless steel grade can achieve specifi c outcomes suitable for diff erent
automotive applications. For instance, crash boxes, door-side impact beams, and EV motor components benefi t from the material’s combination of rigidity and elongation. Folding techniques enable engineers to form origami-like structures that minimise material usage and simplify assembly. With over 320 grade-surface
combinations available, stainless steel surfaces can be aesthetically appealing without requiring additional coatings or treatments — as seen in vehicles like the Tesla Cybertruck and the iconic DeLorean, which incorporate them into both exterior and interior design.
DON’T UNDERESTIMATE DURABILITY Stainless steel has incredible longevity, even in the most demanding environments. Unlike carbon steel, which typically requires protective coatings, stainless steel is inherently corrosion-resistant and can self- heal via chromium oxidation, which reduces maintenance needs. This resilience is particularly crucial
for safety-critical components such as EV battery enclosures. EV battery trays made of stainless steel not only withstand the test of time, but also heat. Some stainless steels can endure temperatures of up to 1250°C for over
Stainless steel is a versatile option for many areas of automotive design
