General Info About 304/304L

304/304L stainless steel plate is one of the most versatile and widely used stainless grades. Due to its lower carbon content and higher chromium composition, this grade is among the best in its class for strength, corrosion resistance, and formability. It is frequently utilized in pharmaceutical and chemical processing equipment, kitchen equipment. In applications where corrosion resistance and welding are required, the ultra low variant 304L is better suited.

More Details About 304/304L

  • Advantages/Disadvantages

    This stainless steel grade is among the most common stainless steel grades, in part because it is so versatile and easy to fabricate. It shows good ductility in the annealed condition, and can be readily drawn and formed for complex shapes. High hardness and strength can be achieved through cold working. This grade demonstrates excellent corrosion resistance and will withstand rural and industrial atmospheric exposure, and weldments are less susceptible to intergranular fractures. One disadvantage is that 304 is non-hardenable by heat treatment.

  • Industries

    This steel grade is used in the food service, textile, chemical processing, petroleum, pharmaceutical, and architecture industries.

  • Applications

    304 stainless is often seen in kitchen equipment, chemical processing equipment, and architectural trim. 304L provides outstanding corrosion resistance and produces better weldments.

  • Machining

    It is machinable.

  • Welding

    It is weldable. However, austenitic stainless steels tend to be at greater risk for cracking at weld joints and sensitization on mechanical properties. Welding with common fusion and resistance methods are recommended for best results, or choosing 304L over 304 when welding is necessary.

  • Heat Treatment

    It is not heat treatable.

Frequently Asked Questions

  • What is the difference between 304 and 304L?


    304L is the ultra low carbon variant of 304 stainless. Lower carbon content is the only chemical difference between these two grades, leading 304L to perform better in corrosive environments and be easier to weld.

  • Why is 304L better for welding than 304?


    The lower carbon content in 304L eliminates chromium carbide precipitation caused during welding, putting 304L at lower risk for intergranular corrosion even in highly corrosive environments.

  • What is the fatigue strength of this grade stainless steel?


    The fatigue strength for 304 stainless is 241 MPa (35 ksi).
