If you're looking for seamless stainless steel tubing with excellent high-temperature performance, corrosion resistance, and tight dimensional tolerances, GNEE's ASTM A511 MT310S stainless steel mechanical tubing is one option. Constructed in accordance with ASTM A511 standards and made from austenitic stainless steel 310S (UNS S31008), our MT310S seamless mechanical tubing excels in harsh environments such as heat treating equipment, furnace components, power generation, and chemical processing.

Advantages
GNEE offers high-quality ASTM A511 MT310S stainless steel mechanical tubing, manufactured from high chromium-nickel austenitic stainless steel. The tubing features a precise outer diameter tolerance of ±0.1 mm, tensile strength ≥550 MPa, and yield strength ≥205 MPa. It delivers superior high-temperature creep resistance compared to standard austenitic stainless steels, making it ideal for applications such as industrial furnace tubes, heat exchanger piping, and high-temperature reactor connections.
In addition, UNS S31008 mechanical tubing provides excellent oxidation resistance and retains its mechanical strength even at temperatures up to 1100°C (2010°F). The annealed MT310S tubing is non-magnetic, making it suitable for use in electronic housings or sensitive instrumentation.
