SS 304 alloy steel is used in the development of pipes. However, the alloy is composed of chromium and nickel, which provide pipes and tubes with various properties. In addition to this, SS 304L has a lower carbon content than 304 alloy steel. This is how it excels at being resistant to intergranular corrosion. Likewise, SS 304H is an alloy for high temperature applications, with high temperature strength and the ability to operate at high temperatures.

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.

The fusion welding properties of stainless steel 304 are excellent with or without fillers. The recommended filler rod and electrode for use with 304 stainless steel is grade 308 stainless steel. For 304L, the recommended packing is 308L. Heavy welded sections may require post weld annealing. The 304L does not require this step. If post weld heat treatment is not possible, grade 321 may be used.

The carbon content of 304L (UNS 30403) is limited to a maximum of 0.03% to prevent sensitization during welding.

304/304L is used almost exclusively for parts that need to be machined, welded, ground or polished, which also require good corrosion resistance. It is a good general purpose stainless steel grade. Good for corrosive environments such as paper and chemical industries and low temperature service. For use where corrosion resistance and good mechanical properties are the main requirements. 304/304L is widely accepted in the dairy, beverage and other food industries where the highest degree of hygiene and cleanliness is essential.

304 Stainless Steel Round Tube In metallurgy, stainless steel, also known as inox steel or inox, is a steel alloy with the highest percentages of iron, chromium, and nickel, with a minimum of 10.5% chromium by mass and a maximum of 1.2% carbon ( by mass). What is most remarkable about stainless steels is their corrosion resistance, which increases with chromium content. The addition of molybdenum improves corrosion resistance in reducing acids and pitting in chloride solutions. Therefore, there are many grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must withstand.

304L stainless steel pipe is a low carbon variant of grade 304 – the steel can be welded without problems with carbon precipitation (the precipitation of chromium carbide when heat is applied during welding depletes the steel of chromium, reducing its resistance to -corrosion/oxidation Effect).

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.
