304L Stainless Steel Solutions
304L Stainless Steel Manufacturer In China
304L stainless steel is a low-carbon variation of the standard 304 grade, belonging to the austenitic stainless steel family. It offers excellent corrosion resistance, superior weldability, and reduced susceptibility to sensitization—a key advantage when used in high-temperature or welded structures.
Compared with standard 304 stainless steel, the “L” grade contains less carbon content (≤0.03%), which significantly minimizes carbide precipitation during welding. As a result, 304L stainless steel maintains its corrosion resistance even after prolonged exposure to heat, ensuring strong and reliable performance in fabrication and assembly processes.
At Hanhuang, we manufacture and supply 304L stainless steel sheets, coils, bars, and custom components for industries requiring precision, strength, and long-term stability. Whether for chemical processing, food manufacturing, construction, or industrial machinery, 304L stainless steel provides dependable material quality that meets international standards and delivers consistent results for large-scale OEM and bulk supply projects.
