what is difference between 304 and 316 stainless steel
Stainless Steel 304 and Stainless Steel 316 are among the most widely used stainless steel grades for industrial piping applications. While both offer excellent corrosion resistance and durability, SS 316 contains molybdenum, providing enhanced resistance to chlorides, chemicals and marine environments.
| Property | SS 304 Pipe | SS 316 Pipe |
|---|---|---|
| Chromium | 18–20% | 16–18% |
| Nickel | 8–10.5% | 10–14% |
| Molybdenum | No | Yes |
| Corrosion Resistance | Excellent | Superior |
| Marine Applications | Good | Better |
| Chemical Resistance | Good | Excellent |
| Cost | Lower | Higher |
| Availability | Widely Available | Moderate |
SS 304 is ideal for general industrial, food processing, pharmaceutical and water treatment applications, while SS 316 is preferred for highly corrosive, chemical processing and marine environments where additional corrosion resistance is required.
