ASME SA312 TP316L Seamless Cold-Drawn Pressure Vessel Tube
ASME SA312 TP316L Seamless Cold-Drawn Pressure Vessel Tube
ASME SA312 TP316L seamless cold-drawn pressure vessel tube is an austenitic stainless steel tube. Due to its low carbon content and the addition of molybdenum, it exhibits extremely high resistance to chloride stress corrosion, pitting corrosion, and crevice corrosion. It is suitable for high-pressure applications and harsh environments, demonstrating excellent mechanical strength and corrosion resistance over a wide temperature range. Its key properties include a minimum tensile strength of 485 MPa, a minimum yield strength of 170 MPa, and an elongation of 35%.
What is the maximum temperature range of 316 stainless steel?
The temperature limit of 316 stainless steel depends on the type of application: for intermittent (non-continuous) use, its maximum temperature is approximately 870℃ (1600℃F); for continuous use in air, the maximum temperature is approximately 925℃ (1700℃F). However, if subsequent resistance to water corrosion is critical, continuous use within the range of 425-860℃ (800-1575℃F) is not recommended, as this temperature range can lead to sensitization and intergranular corrosion.

316L Cold-Drawn Pressure Vessel Tube Material and Structure
Material: Austenitic stainless steel, specifically TP316L, with added chromium, nickel, and molybdenum to enhance its corrosion resistance.
Low Carbon: The "L" in TP316L indicates its low carbon content, minimizing intergranular corrosion during welding.
Seamless Cold Drawing: A seamless structure means no weld seams, providing superior strength and load-bearing capacity. "Cold drawing" is a manufacturing process that improves the dimensional accuracy, surface finish, and mechanical properties of the tubing.
Pressure Vessel Grade: This designation indicates that the tubing is manufactured to high standards and is suitable for high-pressure applications such as power plants or chemical processes.

Gnee Steel specializes in the production of a wide range of stainless steel products. Gnee Steel's product packaging includes: Steel Strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during ocean shipping, and then secured with steel strapping. Wooden Cases/Crates: Pipes are typically packaged in wooden cases or crates to protect the pipes during transportation, especially those that are longer or have larger diameters. Seaworthy Export Packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin Packaging: This prevents rain, seawater, and other external factors from penetrating the export crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in the aerospace, chemical, power, automotive, and nuclear energy sectors, and we can provide customized alloy material solutions based on customer needs.
