304L is preferred. And it lacks a minimum carbon content, which is not ideal for high temperature applications where optimum strength is required, so 304H is the first choice. Thus, 304 is generally limited to rods or sheets that are to be machined into components that do not require welding, or sheets formed in articles, such as kitchen sinks or cookware, which are also not welded.

304 stainless steel has good oxidation resistance in intermittent use up to 870¡ãC and continuous use up to 925¡ãC. However, if corrosion resistance in water is required, continuous use at 425-860¡ãC is not recommended. In this case, 304L is recommended because of its resistance to carbide precipitation.

The low carbon content of 304/304L stainless steel limits the formation of harmful carbides such that this grade is safe for most operations in welded structures, and the service temperature is limited to 800¡ãF. Both hardness and tensile strength can be increased by cold work, which can lead to slight magnetism.
