Stainless steel is steel alloyed with chromium and other possible elements. This produces a steel with good resistance to corrosion. A stainless steel has a minimum of 10.5 % chromium content.
Stainless steel's corrosion resistance is only effective in oxidising environments. When exposed to acids the corrosion resistance of stainless steel is no better than that of mild steel.
Although stainless steel's resistance to atmospheric corrosion is excellent, the presence of chlorides (e.g. in a seaside atmosphere or in salt water) can cause pitting to occur.
Advantages
- Greatly improved corrosion resistance in oxidising environments.
Disadvantages
- Expensive
- Stainless steel can be more difficult to work with
- Difficult to weld stainless steel
