What are stainless steel 317 pipes?
Steel pipes are everywhere. All applications have specific requirements. The stainless steel grade differs according to the needs of the applications. The stainless steel 317 pipe is made up of a grade that has high molybdenum content, along with nickel, chromium, and other elements. The outer diameter of the pipes ranges from 0.125 inches to 1 inch. The wall thickness of the pipes ranges from 0.028 inches to 0.134 inches.
Stainless steel 317 vs 316 pipe
317 stainless steel pipe has 11% nickel, 18% chromium, and 3-4% molybdenum in the composition whereas the 316 grade only has 18% chromium and 10% nickel with less molybdenum content. The ss 317 Welded Pipe also has 2% manganese and 1% silicon. These components make the pipes stronger, more corrosion resistant, and more pitting resistant than the 316 grade. The Grade 317 ERW Pipe and the grade 316 both have 205MPa minimum yield strength and 515MPa tensile strength. Due to the high resistance against stress-induced cracks and other defects, with the increased mix of expensive elements, the 317 grade is expensive.
What is the hardness of 317 stainless steel pipe?
317 stainless steel pipe has a Rockwell B hardness of 85. The elongation at break is 55%. This means that the pipes don’t break so easily, they are hard and tough. The impact resistance of the ss 317 pipe is also high due to the composition. UNS S31700 welded pipe can be used in applications that require high hardness, impact resistance, and abrasion resistance.
Top 5 mistakes most buyers do while buying 317 ss pipe
The first mistake is buying the 317 ss pipe when it is not necessary. The buyers have to decide based on the requirements whether they need to purchase this grade of pipe. Because there are lower grades that are less expensive and can satisfy your needs. If you are sure to buy the 317 grade, then look for the correct supplier.
The second mistake in buying the WNR 1.4449 Seamless pipe is to overlook the hidden costs. The showcased price of the pipes is sometimes way too lower than what they would cost you until delivery at your location. You have to calculate all the costs, time, and administrative tasks involved.
Selecting the wrong type can be a mistake. Select the right size, diameter, and wall thickness, and decide on the shape. You might require square or rectangular pipes. You don’t always have to go with the standard circular pipes.
The fourth mistake is not selecting the right carbon variation. Depending on your application requirement, select the low carbon or high-carbon version.
The fifth mistake is not doing the necessary treatments before shipping. If you don’t do the surface finishes, heat treatments, or any other value-added services at the factory, it will cost you multiple times to do this at your operations site.
What are the manufacturing methods of ss 317 seamless pipes?
The metal is highly malleable and it can be made through cold drawing, hot rolling, or extrusion. The ss 317 Seamless Pipe is made from a single piece of material. It can be a bar or a billet that is pressurized and drawn to get into shape. Since this material has very high heat resistance, hot rolling is also easy on these pipes.
What are the benefits of stainless steel 317 seamless pipes?
Stainless Steel 317 Seamless pipe has resistance to high temperature, high pressure, high mechanical stress, and high oxidation resistance. The material has high strength, good formability, and can be machined. The pipes can also be reused as they don’t produce much rust.
