Maria Pipes and Tubes, based in Kuala Lumpur, Malaysia, is a well-respected manufacturer and supplier of high-quality stainless steel tubing. Their Stainless Steel 304L Welded Tubing stands out for its remarkable corrosion resistance, excellent weldability, and cost-effective production. Crafted to meet international standards like ASTM A249/ASME SA249, these tubes come in round, square, and rectangular shapes, with a variety of diameters ranging from 1/8″ NB to 30″ NB, and schedules from SCH 20 to XXS. They offer delivery options that include annealed, pickled, polished, and bright annealed finishes, catering to a wide array of industrial needs.
Made from an alloy that contains 18–20% chromium and 8–12% nickel, Stainless Steel 304L features a low maximum carbon content of 0.03%. This characteristic helps reduce carbide precipitation and prevents intergranular corrosion, particularly in areas affected by heat during welding. This makes 304L an ideal choice for applications that involve significant welding and require long-lasting corrosion resistance.
