Significant advantages of stainless steel products over other metals:

1. Resists corrosion

2. Retains strength even at high temperatures

3. Hygienic due to the smooth and minimally porous surface (useful for hospitals and food processing plants)

4. Bright aesthetic appearance

5. Easily machined, welded, formed and fabricated

6. Usually non-magnetic - useful for aerospace applications

7. Excellent fatigue and impact resistance - useful in automotive body building

8. High resistance to shock at low and high temperatures

9. Yields durable long-life products
