Stainless Steel 347 and 347H Instrumentation Tubing is an austenitic stainless steel alloy that’s stabilized with niobium to prevent intergranular corrosion during welding and exposure to high temperatures. Its chemical makeup features chromium and nickel, which provide excellent resistance to corrosion and oxidation. The 347H grade has a higher carbon content, boosting its tensile strength and creep resistance at elevated temperatures. Both grades are mechanically robust, offering good ductility, toughness, and the ability to handle pressure, all while maintaining structural integrity under thermal cycling, stress, and continuous operation in tough industrial settings.
