An Overview of Stainless Steel 904L Pipes
Stainless Steel 904L Pipes are low carbon, acid-resistant alloy grade. Aside from having a lower carbon percentage in its alloy, these 904L Grade 1.4539 Stainless Steel Pipes are known to have a greater nickel and molybdenum content. The Stainless Steel 904L Pipes have characteristics such as good activation passivation conversion ability and great corrosion resistance. In fact, the corrosion resistance of the Stainless Steel 904L Pipes is especially noticeable in non-oxidizing acids such as acetic acid, sulfuric acid, formic acid, and phosphoric acid at any concentration and at any temperature.
The pitting resistance of the Stainless Steel Grade 1.4539 Seamless Pipes is high when used in neutral chloride-containing media. Not only is Grade 904l welded pipe resistant to crevice corrosion and stress-related corrosion cracking, but it is also suitable for use in sulfuric acid solution at varied concentrations below 70 °C. Because the carbon content in ASTM A312 uns n08904 1.4539 pipes is low, it is free of carbide precipitation, especially when general heat treatment or welding processes have been performed on the pipes.
Advantages of Stainless Steel 904L Pipes
- Non-magnetic.
- Greater corrosion resistance than Types 316L and 317L.
- Resistance to sulphuric, phosphoric, and acetic acids is high.
- Resistance to crevice and stress corrosion cracking is high.
- Outstanding formability and weldability.
What Makes 904L Steel So Unique?
Its low carbon content makes it resistant to welding sensitization and inhibits intergranular corrosion. It’s used in piping systems, pollution control equipment, heat exchangers, and bleaching systems, among other things.
