A269 TP347H Cold Finished Stainless Steel Pipe
Our A269 TP347H Stainless Steel Seamless Pipe is known for its high tensile strength and corrosion resistance, ensuring service life even in the most demanding conditions.
A269 TP347H Cold Drawn Stainless Steel Pipe is usually made of 18-8 stainless steel with alloying elements such as niobium and titanium. These alloying elements have higher heat resistance and corrosion resistance, suitable for use in chloride environments. At the same time, the addition of carbon content in the A269 TP347H cold worked pipe grade enhances its properties such as high temperature strength, making it an ideal choice for high temperatures.
A269 TP347H Cold Drawn Stainless Steel Pipe Applications can be widely used in petrochemical industry, refineries, shipbuilding, paper industry, marine industry, oil and gas industry, food processing industry and other automotive applications.
