1.4301 Stainless Steel Seamless Tube For Heaters

If you are looking for reliable stainless steel seamless tubes for heating systems and thermal equipment, we offer 1.4301 stainless steel seamless tubes, specifically designed to provide stable performance under continuous heating and moderate pressure conditions.

1.4301 stainless steel is the EN standard grade equivalent to AISI 304, containing approximately 18-20% chromium and 8-10.5% nickel, offering excellent oxidation resistance, good thermal stability, and reliable corrosion resistance in water, steam, and mildly corrosive media.

Our 1.4301 stainless steel round tubes are manufactured using precision hot extrusion or cold drawing processes, ensuring uniform wall thickness, smooth inner surface, and high dimensional accuracy, significantly improving heat transfer efficiency and service life. Minimum tensile strength is 520 MPa, and it possesses good ductility, allowing the pipes to withstand thermal expansion and repeated heating cycles without cracking. Diameter ranges from 6mm to 219mm, thickness from 0.3 to 4.0mm, grain size is 400-600, and surface treatment processes include 180HL, 240HL, and 329HL.

With extensive export experience, we supply 1.4301 stainless steel seamless heating tubes to Europe, the Middle East, Southeast Asia, and South America, serving industries such as electric and gas heaters, heat exchangers, boilers, HVAC systems, food processing equipment, and domestic and industrial water heaters.
