If you're purchasing 317 stainless steel tube or plate, understanding price per kilogram, performance, and supplier selection is crucial for making a cost-effective purchasing decision.
317 (UNS S31700 / EN 1.4449) stainless steel is an austenitic alloy with a higher molybdenum content (3-4%) than 316 stainless steel, providing excellent resistance to pitting, crevice corrosion, and chemical attack, especially in acidic chloride or sulfur-containing environments.

FAQ
Q1: What's the difference between 316 and 317 stainless steel?
317 contains more molybdenum (3–4%), providing superior corrosion resistance, particularly against chlorides and industrial acids.
Q2: Is 317 stainless steel magnetic?
No, it is a non-magnetic austenitic alloy, even after cold working.
Q3: What's the price difference between 317 and 316 stainless steel?
On average, 317 is 10–20% more expensive due to its higher nickel and molybdenum content.
Q4: What are the available delivery conditions?
Mill finish, solution annealed, pickled, or polished. All materials are certified to EN 10204 3.1.
