General Info About 304/304L

304/304L stainless steel tube is one of the most widely used stainless steel grades. It has a low carbon content and high chromium and nickel composition. It is readily drawn and formed, and shows good strength and outstanding corrosion resistance, including protection against intergranular corrosion during welding.

More Details About 304/304L

  • Advantages/Disadvantages

    304 stainless is part of the austenitic steel family. One of the disadvantages of austenitic steels is that it cannot be hardened by heat treatment. This aside, 304 is an incredibly versatile stainless steel grade that can be readily drawn and formed. Both hardness and strength can be improved through cold working. It has good ductility in the annealed condition.  Additionally, 304L demonstrates excellent corrosion resistance given its ultra low carbon makeup.

  • Industries

    304 stainless steel tube can be seen in the aerospace, automotive, food and dairy, textile, pharmaceutical, and architecture industries, among others.

  • Applications

    This grade is frequently purposed in chemical processing equipment across industries, from food and dairy, to pharmaceutical and textiles. It is also utilized for heat exchangers, construction materials, and kitchen equipment.

  • Machining

    It is machinable.

  • Welding

    304 stainless is weldable. Due to added intergranular corrosion protection, 304L performs better 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 tube in the "as welded" state?

    ANSWER:

    The “as welded” state eliminates the need for annealing prior to welding, which saves time and resources. While 304 stainless steel tube can sometimes be used in the “as welded” state, the ultra low carbon in 304L adds protection against intergranular corrosion to produce more durable weldments.

  • How does 304 perform in elevated temperature conditions?

    ANSWER:

    As temperatures increase, let’s say from room temperature to 1600°F, the mechanical properties of 304 will depreciate. For example, ultimate strength will drop from 586 MPa (85 ksi) to 110 MPa (16 ksi).

  • What is the Brinell hardness number (BHN) of this stainless steel grade?

    ANSWER:

    The BHN for 304 stainless in the annealed condition is 150. Once cold drawn, the BHN increases to 277.
