The Stainless Steel 347 and 347H Electropolished Pipes are made from titanium-stabilized austenitic stainless steel, which includes chromium, nickel, and titanium. The 347H variant stands out with its higher carbon content, offering better high-temperature strength and creep resistance. Electropolishing not only boosts corrosion resistance but also eliminates surface imperfections, enhancing the smoothness and cleanliness of the pipe surface. On the mechanical side, these pipes deliver excellent tensile and yield strength, toughness, and fatigue resistance, all while ensuring good weldability and dimensional stability, making them perfect for demanding industrial and hygienic settings.
