Stainless Steel 309H Tubing is characterized by its high levels of chromium and nickel, typically ranging from 22 to 24 percent chromium and 12 to 15 percent nickel, along with an increased carbon content that enhances strength at elevated temperatures. This unique composition ensures excellent oxidation resistance, good corrosion resistance, and a stable austenitic structure. In terms of mechanical properties, 309H tubing delivers high tensile strength, improved creep resistance, good toughness, and reliable performance under continuous heat exposure, while also maintaining weldability and structural integrity. It showcases moderate yield strength, controlled elongation, and consistency during fabrication, forming, and high-temperature service conditions.
