Stainless Steel 348H Tubing is crafted from a stabilized austenitic stainless steel alloy that includes chromium, nickel, and niobium, which enhances its resistance to carbide precipitation at high temperatures. The “H” grade features a higher carbon content, boosting its strength and creep resistance in high-temperature settings. This tubing showcases impressive mechanical properties, such as high tensile strength, good ductility, and robust thermal stability. It effectively resists oxidation, intergranular corrosion, and stress-corrosion cracking, making it a reliable choice for long-term use in high-heat environments. Its well-balanced composition ensures dependable performance in applications that demand structural integrity under continuous thermal exposure.
