FAQ's

What is 317 stainless steel tube?

Stainless steel 317 is an austenitic chromium-nickel-molybdenum alloy known for its outstanding resistance to corrosion, particularly in environments containing sulfuric and other aggressive acids. It provides excellent protection against pitting, crevice, and general corrosion, along with high tensile strength and durability. This alloy also maintains its mechanical properties and oxidation resistance at elevated temperatures, making it suitable for use in chemical processing, marine, and high-temperature industrial applications.

Does 317 stainless steel tube rust?

Yes, 317 stainless steel tube is highly resistant to corrosion and does not usually rust, even in environments with strong acids or high chloride levels. Its high molybdenum, chromium, and nickel content offers exceptional protection against pitting, crevice, and general corrosion, making it well-suited for demanding industrial applications.

What is 317 stainless steel tube used for?

317 stainless steel tubes are widely used across industries that demand superior corrosion resistance, high-temperature strength, and chemical stability. It is commonly found in chemical processing, petrochemical, power generation, oil and gas, pulp and paper, pharmaceutical, food processing, and desalination applications. Common uses include heat exchangers, boilers, steam lines, chemical reactors, and pipelines, where durability and resistance to corrosive environments are essential.

What is the difference between SS 316 and 317 tube?

317 stainless steel is an austenitic chromium-nickel-molybdenum alloy that offers higher corrosion resistance, strength, and durability than 316 stainless steel due to its greater molybdenum and nickel content. While 316 is ideal for marine and chloride-rich environments, 317 performs better in acidic and high-temperature conditions. However, 317 is more expensive because of its enhanced composition. Both grades are widely used across industries, with 317 suited for chemical processing and high-temperature equipment, and 316 commonly used in food, medical, and marine applications.
