304 / 304L / 304H Stainless Steel Pipe & Tube
304 series stainless steel pipes and tubes are widely used austenitic stainless steel products known for excellent corrosion resistance, good formability, and reliable mechanical properties. At Voyage Metal, we supply 304, 304L, and 304H stainless steel pipes and tubes for global industrial, engineering, and fabrication projects.
Product Information
304 stainless steel pipe is the standard grade, suitable for general corrosion-resistant applications. 304L is the low-carbon version, designed to minimize carbide precipitation during welding and improve resistance to intergranular corrosion. 304H contains higher carbon content, offering enhanced strength for elevated temperature service.
Voyage Metal provides stainless steel pipes and tubes with stable quality, flexible specifications, and export-oriented packaging to meet international standards.
