TP304 Seamless Stainless Steel Tube find widespread use in various industries due to their excellent properties. Here are some key applications:
Remember that 304 stainless steel pipes are versatile, making them a preferred choice across diverse sectors!
The stainless steel alloys AISI 304 and AISI 304L are the best known and most widely used chromium-nickel steels. Their excellent corrosion resistance, high strength and low carbon content make these austenitic steels particularly suitable for applications requiring welding.
304, 304H and 304L all possess the same nominal chromium and nickel content and thus possess the same corrosion resistance, ease of fabrication and weldability. The difference between 304, 304H and 304L is the carbon content which is >0.03, >0.05 and <0.03 respectively.
The carbon content of 304H (UNS S30409) is restricted to 0.04–0.10%, which provides optimal high temperature strength.
The carbon content of 304L (UNS 30403) is restricted to a maximum of 0.03%, which prevents sensitization during welding.
The carbon content of 304 (UNS 30400) is restricted to a maximum of 0.08%. Thus 304 is not useful for corrosive applications where welding is required such as tanks and pipes where corrosive solutions are involved, thus, 304L is preferred. And its lack of a minimum carbon content is not ideal for high temperature applications where optimal strength is required, thus, 304H is preferred. Thus 304 is typically restricted to bars that will be machined into components where welding is not required or thin sheets that are formed in articles such as kitchen sinks or cookware that are also not welded.
Carbon content has a strong influence on room temperature strength and thus the specified minimum tensile properties of 304L are 5 kilopounds per square inch (34 MPa) lower than for 304 (515 MPa). However, nitrogen also has a strong influence on room temperature strength and a tiny addition of nitrogen produces 304L with the same tensile strength as 304. Thus, practically all 304L is produced as dual certified 304/304L, meaning it meets the minimum carbon content of 304L and also meets the minimum tensile strength of 304.
