General Info About 304/304L

304/304L stainless steel bar has low carbon content and high chromium composition. It has good strength, ease of formability, and outstanding corrosion resistance, including protection against corrosion when welding.

More Details About 304/304L

  • Advantages/Disadvantages

    304 is an austenitic steel. One disadvantage of austenitic steels is that they are non-hardenable by heat treatment. However, this stainless steel grade can be readily drawn and formed and exhibits good ductility in the annealed condition. Both hardness and strength can be improved through cold working. Additionally, 304 and 304L demonstrate excellent corrosion resistance.

  • Industries

    304 stainless steel bar is frequently used in the aerospace, automotive, food and dairy, textile, chemical processing, petroleum, pharmaceutical, and architecture industries.

  • Applications

    Heat exchangers, construction materials, kitchen equipment, chemical processing equipment, and architectural trim are some common applications for this grade.

  • Machining

    It is machinable.

  • Welding

    It is weldable. Due to added corrosion protection, 304L should be selected over 304 where weld quality in a corrosive environment is a major factor.

  • Heat Treatment

    It is not heat treatable.

Frequently Asked Questions

  • Can you use 304 stainless steel bar in the "as welded" condition?

    ANSWER:

    The “as welded” condition eliminates the need to anneal the steel at joint sites. Not having to anneal the steel can save time and resources. While 304 stainless steel bar can sometimes be used in the “as welded” condition, 304L is more often used in the “as welded” condition due to its added protection against corrosion.

  • What are the main alloying elements for this grade?

    ANSWER:

    Chromium and nickel are the main alloying elements for this stainless steel grade. It contains 18% and 20% chromium and 8% to 12% nickel.

  • What is the yield strength for this grade stainless?

    ANSWER:

    The yield strength for 304 is 290 MPa (42 ksi) and the yield strength for 304L is 276 MPa (40 ksi).
