General Info About 316L

316L stainless steel tube is a highly corrosion resistant chromium nickel austenitic stainless steel. Due to the addition of molybdenum, it is protected in corrosive environments and can be used in chemical processing equipment common in the textiles, paper and pulp, and industry, as well as for heat exchangers and other parts exposed to marine atmospheres.

More Details About 316L

  • Advantages/Disadvantages

    This stainless steel grade can be more easily welded than comparable stainless steels. It is highly ductile and conveniently formed. However, as with all austenitic steel grades, it cannot be hardened by heat treatment and is not magnetic.

  • Industries

    It is frequently found in industries dealing with corrodent exposure like marine environments. This includes the food and dairy, brewing, textile, pulp and paper, chemical processing, pharmaceutical, and biotech industries.

  • Applications

    Storage tanks, shipping vessels and valves, digesters, chemical, paper, and textile processing equipment as well as applications exposed to elevated temperatures and where corrosion resistance is a critical factor are common applications for this stainless steel grade.

  • Machining

    It is machinable.

  • Welding

    It is weldable. Molybdenum makes this stainless steel product easier to weld than other austenitic stainless steels and weldments are less likely to experience intergranular corrosion, pitting, creep, and cracking.

  • Heat Treatment

    It is not heat treatable.

Frequently Asked Questions

  • Why is 316L more corrosion resistant than 316 stainless steel?

    ANSWER:

    It’s easy to confuse 316 and 316L stainless steels, however a few key differences make 316L a more sought after stainless steel product. For one, the L indicates that this grade is the ultra low carbon variant. In this case, what is primarily a chromium and nickel based stainless product, the 316L variant also includes the addition of molybdenum, which is what gives this grade a particular advantage when it comes to highly corrosive environments.

  • In what finishes is 316L available?

    ANSWER:

    It is available in 2B #3 and #4 polish.
