Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 309H Pipes, designed for applications requiring exceptional high-temperature strength, oxidation resistance, and durability. These pipes are ideal for furnaces, heat exchangers, boilers, gas turbines, and industrial equipment exposed to extreme thermal conditions. Each pipe is manufactured with precision and undergoes stringent quality control to ensure consistent performance. Clients rely on 309H Pipes from Walid Stainless for reliable, long-lasting, and high-performance solutions in demanding high-temperature and industrial environments.
Stainless Steel 309H Pipes are made from a high-chromium, high-nickel austenitic stainless steel alloy containing approximately 23% chromium and 13% nickel, with higher carbon content to enhance tensile strength at elevated temperatures. This composition provides excellent oxidation resistance, corrosion resistance, and creep strength. These pipes typically exhibit tensile strength between 600–750 MPa and hardness around 180–220 HB. The austenitic structure ensures mechanical durability, thermal stability, and resistance to scaling. 309H Pipes are suitable for high-temperature industrial applications requiring long-term reliability, mechanical strength, and corrosion resistance.
