What Is 304L Stainless Steel Pipe?

304L is the low-carbon version of 304 stainless steel. Its lower carbon content helps reduce the risk of chromium carbide precipitation during welding, making it suitable for welded piping and fabricated stainless steel components.

304L provides good general corrosion resistance and is widely used where corrosion resistance and weldability are required.

304L Stainless Steel Pipe Properties

Corrosion resistance: Suitable for many atmospheric and mildly corrosive environments.

Weldability: Low carbon content makes 304L suitable for welded structures and piping.

Formability: Can be formed and fabricated using common stainless steel processing methods.

Surface finish: Available with different finishes according to application and processing requirements.

304 vs 304L Stainless Steel Pipe

The main difference between 304 and 304L is carbon content.

Property	304 Stainless Steel	304L Stainless Steel
Carbon Content	Higher	Lower
Corrosion Resistance	Good	Good
Weldability	Good	Well suited to extensive welding
Typical Use	General applications	Welded piping and fabricated components
UNS	S30400	S30403

304L is often selected when welding is an important part of fabrication. The appropriate grade should be selected according to the application, design and applicable standard.
