Stainless steel 304L tubes are low-carbon versions of the 304L grade, with excellent weldability and corrosion resistance. These tubes are made up of nickel, chromium, carbon, silicon, manganese, phosphorus, sulfur, nitrogen, and iron. The low carbon content reduces carbide precipitation, particularly during welding. These tubes are manufactured using processes such as seamless extrusion or welded forming, and they are cold-worked for added strength and finish. Preston Pipes & Alloys is a top 304L stainless steel tube supplier, known for producing high-quality products that meet industry standards.
304L stainless steel tubes have high tensile strength of 485 MPa and a minimum yield strength of 170 MPa to withstand pressure. Their hardness, measured on the Brinell scale is 201 HB. These tubes are tough, easy to form, and handle high heat and corrosive settings well. ASTM A213 304L Seamless Tubes are widely used in chemical processing, food handling, heat exchangers and architectural structures. UNS S30400 Tube work reliably across many environments.
Our tubes are available in a wide range of specifications. Standards include ASTM A/ASME SA213, A269 and A249. Sizes range from 1/8" NB to 30" NB, with thickness options between 0.35mm to 6.35mm and OD from 0.1mm to 1.2mm. Buyers can choose from seamless, ERW, welded, fabricated, and LSAW types. Tube forms include round, square, rectangular, and hydraulic. Available in lengths like single random, double random or custom cuts. End finishes of AISI 304L Seamless Tube include plain, beveled, and threaded options.
Each UNS S30400 Tube goes through quality checks such as hydro testing, visual checks, and dimensional inspections. We also conduct PMI, ultrasonic, and pressure tests as needed. As a 304L stainless steel tube stockist, we ensure tubes are securely packed in wooden boxes or bundles with end caps to avoid damage during transport.
