304 304l Stainless Steel Tube
As stainless heat-resistant steel, 304 steel pipe is the most widely used in food equipment, general chemical equipment, and atomic energy industry equipment.
What is the difference between stainless steel 304, 304H and 304L?
Stainless steel pipe 304 is a type 18-8 austenitic stainless steel containing approximately 18% chromium and 8% nickel. In addition, it contains small amounts of elements such as carbon, manganese, silicon and phosphorus. 304 stainless steel pipe has good corrosion resistance and welding properties and is suitable for general purpose applications.
Stainless steel 304H pipe is a high-carbon version of stainless 304 steel pipe, which has a higher carbon content, usually between 0.04% and 0.1%. The high carbon content makes 304H steel pipes have better high-temperature strength and corrosion resistance, making them suitable for applications in high-temperature environments, such as stoves, burners and high-temperature pipes.
304L steel pipe is a low-carbon version of stainless steel 304, with its carbon content controlled below 0.03%. The low carbon content helps improve the intergranular corrosion resistance of 304L, making it suitable for welded structures and applications in some special environments, such as the chemical industry and medical equipment.
Due to the presence of high carbon content, stainless steel 304H steel pipe has better oxidation resistance and high temperature strength in high temperature environments. In comparison, the performance of 304 and 304L alloy steel pipes is slightly reduced in high temperature environments.
Stainless steel 304 has good corrosion resistance and can resist the erosion of general corrosive media, such as water, most organic acids and inorganic acids.
Due to the addition of high carbon content, 304H stainless steel pipes have better corrosion resistance in high temperature environments and can resist the erosion of acidic gases and high temperature corrosive media.
Stainless steel seamless 304L steel pipe improves its resistance to intergranular corrosion by reducing the carbon content. It has good corrosion resistance against corrosive media in some special environments, such as acidic chloride solutions and seawater.
