SS 304L contains a maximum carbon content of 0.03%, while SS 304 contains up to 0.08%. The lower carbon content of SS 304L minimizes carbide precipitation during welding and improves resistance to intergranular corrosion.
| Property | SS 304L Pipe | SS 304 Pipe |
|---|---|---|
| Carbon Content | 0.03% Max | 0.08% Max |
| Weldability | Excellent | Very Good |
| Intergranular Corrosion Resistance | Superior | Good |
| Post Weld Heat Treatment | Generally Not Required | May Be Required |
| Corrosion Resistance | Excellent | Excellent |
| Strength | Slightly Lower | Slightly Higher |
| Fabrication | Excellent | Excellent |
| Typical Applications | Welded Process Piping | General Industrial Service |
SS 304L is preferred for welded piping systems, chemical processing equipment, pharmaceutical plants and applications where resistance to weld decay and intergranular corrosion is important.
