Our ASTM A312 TP304L Stainless Steel Pipe is manufactured from austenitic stainless steel, offering excellent corrosion resistance, good formability, and weldability. The "L" grade denotes a maximum carbon content of 0.03%, which minimizes the risk of carbide precipitation during welding. This makes ASTM A312 TP304L particularly suitable for applications requiring high resistance to intergranular corrosion. We supply both seamless and welded types, ensuring a reliable solution for various industrial needs.

FAQ
Q1: When should I choose TP304L over standard TP304?
A: Choose ASTM A312 TP304L when the application involves welding, especially for sections that cannot be annealed afterward, or when the service environment is highly corrosive and susceptible to intergranular attack. The low carbon content prevents harmful carbide formation.
Q2: Can you provide pipes with special surface finishes?
A: Yes. We can supply ASTM A312 TP304L pipes with various surface finishes, such as polished or pickled, upon request. Please specify your requirements.
Q3: What documentation accompanies the shipment?
A: Each shipment includes a complete set of documents: Commercial Invoice, Packing List, Bill of Lading, and the crucial EN 10204 3.1 Material Test Certificate for quality assurance.
Q4: What is your minimum order quantity (MOQ)?
A: Our MOQ is flexible. We cater to both large projects and smaller trial orders. Contact us with your specific needs for a tailored solution.
