Key Points
- Although tin is used in various alloys and has its own unique characteristics, it is not a common component of stainless steel.
- Adding tin to stainless steel is not common and is not considered a standard ingredient in stainless steel production.
- Stainless steel is primarily composed of iron, along with chromium, nickel, and other elements.
- Chromium provides corrosion resistance to steel.
- It exhibits exceptional corrosion resistance due to the formation of a very thin layer of Cr2O3 on the surface.
- Nickel is usually added to stainless steel to increase its strength and hardness. It also improves corrosion resistance, especially in acidic environments.
- An important type of stainless steel is often described as 18/8 steel where the chromium and nickel percentages are 18 and 8 respectively.
