Introduction of 304L Stainless Steel pipe – Low Carbon Corrosion-Resistant Alloy
YASCO 304L stainless steel is a low-carbon variant of the classic 304 austenitic stainless steel, designed to minimize carbide precipitation during welding and enhance corrosion resistance in harsh environments. With its excellent formability, weldability, and durability, 304L is widely used in industries requiring hygienic standards, structural integrity, and long-term performance.

Manufacturing Processing
- Seamless 304L stainless steel pipe: manufactured through hot rolling, cold rolling, or cold drawing processes, suitable for high-pressure, high-precision scenarios.
- Welded 304L stainless steel pipe : using straight seam or spiral welding technology, mostly used for decoration and low-pressure pipeline systems.

Applications of 304L Stainless Steel Pipe
| Scenario | Recommended Grade | Reason |
| Food Processing Equipment | 304L | Low carbon meets hygienic standards; no post-weld treatment required. |
| Architectural Decor (Non-Welded) | 304 | Lower cost and slightly higher strength. |
| Chemical Piping (Welded) | 304L | Avoids corrosion risks in welded zones. |
| High-Temperature Non-Welded Parts | 304 | Slightly higher carbon enhances high-temperature strength. |
