The 304 stainless steel pipe is a grade of metal that is highly resistant to corrosion, intergranular corrosion, and moderately aggressive organic acids. This is made possible because it is an 18/8 steel, which means it has been alloyed with 18 percent chromium and 8 percent nickel. In some cases, 304L steels show lower corrosion rates than 304 alloys. However, 304L, 304 and 304H show uniform performance when placed in environments that are corrosive. This metal is also resistant to oxidation when serviced in temperatures up to 1600 degrees F or continuous service at a temperature of 1690 degrees F.
304L resists heat well. It shows to have greater carbide precipitation resistance compared to 304 alloys, allowing it to be serviced continuously at temperatures between 800 and 1580 degrees F.
304L stainless steel pipes are austenitic, making it an ideal choice for forming moving parts. It is the most versatile of the alloys, making it a widely used metal in various industries, including food, beverage, dairy, and chemical. Because it can be deeply drawn, it is commonly used to make pots, pans and other hollowware.
This metal has outstanding drawing, formability, machinability, and weldability. Fabricating this grade of steel is easy. Non-magnetic steels like this are considered to be the easiest to weld out of the high-alloy steels. Different resistance welding processes and fusion can be used. In order to strengthen the tensile and hardness of this steel, cold working is needed. Heat treatment cannot be used for this purpose. Other applications that this is commonly used for include chemical containers, welded screens for mining, aerospace technology, automotive equipment, and food processing equipment.
