ASTM A213 TP310S stainless steel heat exchanger tubes
As a leading manufacturer and supplier of ASTM A213 TP 310/310S tubing, GNEE specializes in providing high-performance austenitic stainless steel tube solutions to global buyers. Our products include seamless tubes, welded tubes, ERW tubes, U-tubes, and custom instrument tubes, available in customized lengths to fully meet the demanding requirements of various industrial applications.
Our ASTM A213 SS 310 seamless tubes contain 24%-26% chromium and 19%-22% nickel, with small amounts of silicon and manganese added. This composition allows them to withstand temperatures up to 1200°C under continuous operation while maintaining excellent oxidation resistance and mechanical stability, far exceeding the limits of traditional alloy steels/carbon steels. The chemical composition remains stable at high temperatures without loss of strength, making it the preferred choice for heat treatment and chemical industries. Compared to 304/309 alloys, the high chromium content enhances oxidation/carburization corrosion resistance. ASTM A213 310 seamless condenser tubes are particularly suitable for high-temperature applications such as heat treatment and chemical equipment.

Testing and Inspection
We conduct comprehensive, independent quality inspections throughout the entire process, covering material composition, intergranular corrosion, hardness, pitting corrosion, chemical composition analysis, and third-party testing. We also perform additional specialized tests based on customer application requirements to ensure that every pipe meets the required standards.


Highest quality packaging and shipping
ASTM A213 TP 310/310S Seamless Tube may be furnished bare or coated and with capped ends. tubes up to 3" OD will be supplied in bundles. In order to prevent rust during sea shipment, bundles of ASTM A213 TP 310/310S Stainless Steel Seamless Tubes may be wrapped with polypropylene sheets, and secured with flat steel bands. Over 3" OD will be supplied loose.
