Product Description

Product Description

Material Summary

TP309 Stainless Steel Tubing are austenitic chromium-nickel ss that provide excellent corrosion resistance and heat resistance plus good strength at room and elevated temperatures. The lower nickel content of 309 tubes improves resistance to sulfur attack at high temperatures. The high chromium and nickel content of SUS 309 Pipe & tubes provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic 304.

The steel resists oxidation up to 1900°F (1038°C) under non-cyclic conditions
Because of its high chromium and low nickel content, 309 can be utilized in sulfur containing atmospheres up to 1832°F (1000°C). The steel is not recommended for use in highly carburizing atmospheres since it exhibits only moderate resistance to carbon absorption. 309 can be utilized in slightly oxidizing, nitriding, cementing and thermal cycling applications, albeit, the maximum service temperature must be reduced.
