304L Stainless Steel Pipe comes in various forms and sizes. It can be welded, fabricated or seamless and used for a range of applications; the most popular being water supply systems.

These tubes are an ideal choice for various water pump and piping systems due to their superior durability. They’re resistant to corrosive chemicals and easy to machine. Furthermore, these tubes can also be utilized in water heaters, septic tanks and other plumbing applications.

This stainless steel is a low carbon “18-8” austenitic chromium-nickel alloy with superior resistance to intergranular corrosion after welding or stress relieving. It contains less carbon than other AISI 304 grades but still maintains the same hardness and tensile strength.

304L’s ductility is further increased due to its reduced carbon content, making the tube more malleable and ideal for welding. This makes 304L an ideal choice for pipe and fittings since it can be joined using various methods such as plasma welding or gas welding.

For applications requiring good ductility, stainless steel grades with chromium and nickel content such as 304L are widely used. With its low carbon content and higher amounts of both elements, 304L makes for a suitable option.

Another advantage of 304L is its superior oxidation resistance. It can withstand temperatures up to 1600degF, making it perfect for applications requiring high levels of protection against oxidation.

304L is not only corrosion-resistant but also chemically inert. This is thanks to its high chromium and nickel content, which helps combat corrosion. As such, 304L makes an ideal choice for plumbing applications due to its resistance to rust, scale and other damaging elements.

In addition to its durability, 304L is an ideal choice for piping and fittings due to its low carbon content. This allows it to be welded easily, as well as giving it a higher ductility factor than other stainless steels.

It is essential to be aware that materials with carbon content greater than 0.03% will be susceptible to grain boundaries. Fortunately, many companies have discovered ways to modify the carbon content in order to help avoid this issue.
