Stainless steel is a popular material used for various applications, and 317 stainless steel is a particular type that can offer numerous advantages. 317 stainless steel pipes are characterized by their high corrosion resistance, excellent strength, and durability, making them a preferred choice for many industries. In this blog post, we will take an in-depth look at the properties and characteristics of 317 stainless steel pipes and their most common applications.
What are 317 Stainless Steel Pipes?
317 stainless steel pipes are an alloy for industrial and commercial products. This alloy is made up of a combination of austenitic chromium, nickel, molybdenum, and nitrogen, making it highly resistant to corrosion and oxidation at higher temperatures. It also offers excellent creep strength, toughness, and tensile strength at elevated temperatures. 317 Stainless steel is particularly suitable for use in applications involving strong organic acids like acetic acid and sulfuric acid due to its high chromium content acting as a barrier against oxidation. Additionally, these pipes have excellent weldability thanks to their higher carbon levels compared to other stainless steel alloys making them perfect for intricate designs that require welding as part of the fabrication process without any loss in strength or performance.
Properties
317 stainless steel pipes are austenitic stainless steels that contain molybdenum. This gives the alloy increased resistance to chemical attack and corrosion.
2. The higher molybdenum content in 317 stainless steel pipes also gives the alloy a higher resistance to pitting and crevice corrosion in chloride-containing environments.
3. The addition of molybdenum also makes 317 stainless steel pipes more resistant to general corrosion than 304 or 316 stainless steel.
4. 317 stainless steel pipes also have a higher yield strength than 304 or 316 stainless steel, making them suitable for use in high-pressure applications.
5. The higher carbon content of 317 stainless steel pipes also makes the alloy less weldable than 304 or 316 stainless steel.
Characteristics
317 stainless steel pipes are austenitic chromium-nickel stainless steels that contain molybdenum.
Due to the addition of molybdenum, 317 stainless steel pipes offer better overall corrosion resistance than 304 stainless steel pipes.
317 stainless steel pipes are more resistant to pitting and crevice corrosion in chloride environments than conventional chromium-nickel austenitic stainless steels such as 304 stainless steel pipes.
317 stainless steel pipes can be used in applications with sulfuric acids, such as in the chemical processing industry.
Some of the other benefits of using 317 stainless steel pipes include improved resistance to pitting when exposed to high temperatures and greater creep strength than other austenitic stainless steels.
