AISI 317L Stainless Steel Chemical Composition, Grades, Table and PDF Online

AISI 317L represents as an austenitic stainless steel characterized by very high resistance to corrosion and the ability to maintain high strength at temperatures above the standard. Its chemical structure has chromium, nickel, molybdenum, and low carbon content in the composition, that makes the resistant to all corrosives environments, including the acidic and chloride-containing ones. AISI 317L grades are assigned according to their composition and features and are mixed properly to fit operations in chemical processing, food processing and health-care industries perfectly. A comprehensive and conveniently located tables, chart and PDF recourses that specify its degree and mechanical properties, as well as corrosion and wear resistance, are always accessible, assisting engineers, designers, and manufacturers in the opting of the suitable material for their construction. This complete information provides guidelines that will ensure that the best material has been chosen for the purpose, to guarantee that it works best in situations that are rigorous.

AISI 317L Austenitic Stainless Steel Chemical Composition And Grade Table

AISI 317L is a low-carbon, molybdenum-bearing austenitic stainless steel commonly regarded for its excellent corrosion resistance in a wide variety of corrosive media, from simple atmospheric conditions up to strong acids or chloride-containing environments. The chemical composition of the alloy falls typically within the range of 18-20% chromium, 11-15% nickel, 3-4% molybdenum and no more than 0.03% carbon. This alloying step increases its ability to ward off chloride ion corrosion and pitting. The 317L grade has better resistivity to acidic and chloride conditions than the 304 and 316 steels used conventionally. It is used for various industries such as chemicals, pulp and paper, drug manufacturing, and food processing.

The Advantages and Disadvantages of AISI 317L Austenitic Stainless Steel

    Advantages:

  • Corrosion Resistance: AISI 317L stainless steel has been found to have superior resistance to corrosion as it is perfect for use in the severe industrial conditions where there is exposure to acidic and chloride solutions.

  • High Temperature Performance: AISI 317L has enhanced chromium, nickel, and molybdenum content its important for use in high-temperature conditions such as in some heat exchangers and furnace parts.

  • Weldability: As for weldability, AISI 317L is relatively easily welded in various processes while retaining good corrosion resistance.

  • Formability: This stainless steel grade has high formability, thus can be easily moulded into different shapes to suit various uses in industries like pharmaceutical, food and chemical industries.

  • Low Carbon Content: The low carbon content in AISI 317L reduces the probability of sensitization and intergranular corrosion, thus making it more durable and dependable in corrosive conditions.

    Disadvantages:

  • Cost: Compared to standard grades AISI 317L stainless steel cost slightly more owing to their improved corrosion resistance and use of alloying constituents which may affect project costs.

  • Machinability: On the other hand, AISI 317L is relatively easy to cold and hot-form, however, due to its high work hardening rate and heat build up when it is being machined, the process may need special tools and care.

  • Availability: The material AISI 317L may be less readily available than other stainless steel grades and this could influence practical issues such as lead times or bulk purchasing.

  • Sulphide Stress Cracking: AISI 317L is however, sensitive to sulphide stress cracking in H2S environments and this makes it very important that care is taken in the choice of material and operation of facilities in this industry.

  • Maintenance: AISI 317L stainless steel is quite resistant to corrosion but should be maintained and cleaned regularly to remain resistant to bad environments like the chemical and marine environments.
