347 Stainless Steel Seamless Pipe
Short Description:
347 Stainless Steel Seamless Pipe: High-Temperature Resistance & Corrosion Protection.
Stainless Steel Pipe Roughness Testing:
347 Stainless Steel Seamless Pipes are made from a stabilized grade of stainless steel, designed to offer excellent resistance to intergranular corrosion, particularly in high-temperature environments. These pipes are ideal for applications requiring superior creep strength and oxidation resistance, such as in chemical processing, power generation, and high-heat exhaust systems. With added niobium, 347 stainless steel provides enhanced stability, preventing carbide precipitation and maintaining its strength in temperatures up to 1500°F (816°C). This makes 347 stainless steel seamless pipes perfect for demanding environments requiring durability and long-term reliability.
