The composition of stainless steel
The performance of stainless steel mainly depends on three key elements.
| Element | Role | Benefit |
|---|---|---|
| Chromium (Cr) | Naturally protects the steel against corrosion. | Ensures excellent rust resistance and long-lasting durability. |
| Nickel (Ni) | Improves corrosion resistance and stabilises the steel structure. | Provides a lasting shine and a premium finish. |
| Carbon (C) | Increases the hardness of the steel. | Produces high-performance knife blades that retain their sharpness for longer. |
