An Overview of 904L Stainless Steel Pipes: 

904L Stainless Steel Pipes: 

904L stainless steel pipe is a high–alloy austenitic stainless steel pipe with a high molybdenum content. It has excellent corrosion resistance in a wide range of corrosive media, including sulfuric acid, nitric acid, phosphoric acid, and chlorides. It is also resistant to pitting and crevice corrosion and provides excellent resistance to stress corrosion cracking.

904L stainless steel pipe is ideal for use in chemical processing, oil and gas production, petrochemical and pharmaceutical industries, as well as in industrial and marine applications. It also offers superior weldability, forming, and machinability. 904L stainless steel pipe is highly durable and can withstand extreme temperatures, making it an ideal material for use in high–temperature applications. Additionally, its unique combination of strength, ductility, and corrosion resistance makes it an ideal choice for a range of industries.

Uses of 904l stainless steel pipe 

1. Corrosion Resistance:

904L stainless steel pipe has excellent corrosion resistance, especially in chloride-containing media and other non-oxidizing media. It has good corrosion resistance to many organic and inorganic acids and alkalis.

2. Good Weldability:

904L stainless steel pipe has good weldability. It has good welding performance in the atmosphere, and good welding performance in acid, alkali, and other media.

3. Good Oxidation Resistance:

904L stainless steel pipe has good oxidation resistance in the air and can be used for a long time at about 850℃.

4. High Temperature Strength: 904L stainless steel pipe has good high-temperature strength and can be used for a long time at about 950-1000℃.

5. Low Carbon Content:

904L stainless steel pipes have low carbon content, which is beneficial to reduce the precipitation of chromium carbide during welding and improving the corrosion resistance of welded joints.
