317 stainless steel pipe has high corrosion resistance. Due to the high molybdenum content in the alloy, it has excellent resistance to pitting corrosion, especially in chloride environments. Since ASME SA312 UNS S31700 pipe is resistant to corrosion and oxidation, it is important in many industries where it is used for sanitary equipment. SS 317 ERW pipe is used in marine, marine components, pulp and paper applications and components for the oil and gas industry.
317 stainless steel pipe is an improved version of 316 stainless steel, which is tougher than 304 stainless steel. This is due to the high content of nickel and chromium in its composition, which makes 317 stainless steel pipe not only have high hardness, but also have higher strength than ordinary stainless steel pipes. It welds using fusion and resistance methods. The processing performance of stainless steel SUS 317 pipe is very good, whether it is bending, molding and other processing methods, it can be completed well. DIN 1.4449 stainless steel pipes can be used in high temperature environment up to 800ºC, very suitable for use in high temperature furnace piping system.

Production of 317 Stainless Steel Pipe
HT PIPE is a professional 317 stainless steel pipe suppliers, we select raw materials with good quality and stable composition to produce the size and shape required by customers. In the production process, the welded 317 stainless steel pipe is stretched by a cold drawing machine, and the strength and surface smoothness of the 317 stainless steel pipe can be improved after processing. The cold-drawn SS 317 SCH 10 pipe is pickled to remove oxides and corrosion on the surface and improve the corrosion resistance of the stainless steel pipe. Finally, the size inspection, surface cleaning and other processes are carried out to make the 317 stainless steel pipe meet the standard requirements, and then it can be put into the market.
