Guide to 904L Stainless Steel Pipe

904L Stainless Steel Pipe

Low carbon, high composite austenitic 904L Stainless Steel Pipe is non-balanced out. With 6% molybdenum content, 904L’s corrosion resistance falls between super austenitic levels and 316L’s regular austenitic values.

The expansion of copper to this grade significantly improves its resistance to solid degrading acids, particularly sulphuric corrosive. Stainless steels with a 904L designation have a high virtue rating and less sulfur. They can be machined using any common method. To achieve the best anxiety consumption splitting protection under normal circumstances, this steel grade should be arrangement treated after icy working. It is also remarkably resistant to chloride attack, including setting or complete consumption as well as stress corrosion breaking. Stainless steels made of 904L offer excellent oxidation resistance.

This grade is unattractive under any circumstance and is incredibly formable and weldable. In any case, at high temperatures, particularly above 400°C, this grade’s supplemental solidity decreases. Additionally, the austenitic structure offers this grade exceptional strength, even at cryogenic temperatures.

The temperature range for heat treating 904L Stainless Steel Pipe is 1090°C to 1175°C, followed by rapid cooling. The extremely liberal amounts of the expensive components nickel and molybdenum are included in 904L. These assessments should be solidified with warm therapy.

It is used less frequently than it once was because a significant number of the applications where this grade previously performed well may now be supplied at a lower cost by duplex stainless steel 2205. Every single conventional technique can be used to weld 904L stainless steel.

Applications

  • Oil refinery components
  • Pulp and paper processing industries
  • Gas scrubbing plants
  • Wiring in electrostatic precipitators
  • Acetic, phosphoric, and sulphuric acid processing plants
  • Seawater cooling devices

Excellent resistance to chlorine attack and warm seawater corrosion can be found in 904L stainless steels. Due to the high levels of nickel present, grade 904L exhibits greater than average resistance to stress corrosion cracking. Grades 304L and 310L are more nitric acid resistant than the alloy.
