Stainless Steel 904L Chemical Composition

Stainless Steel 904L content with low carbon material. This excessive alloy stainless steel 904L has copper brought to it to reinforce its resistance to lowering acids like sulfuric acid. Also, stress corrosion cracking and crevice corrosion are vain for the steel. Non-magnetic stainless steel grade 904L has outstanding formability, durability, and weldability. High concentrations of expensive components, like nickel and molybdenum, are found in stainless steel grade 904L. Today, less expensive duplex stainless steel 2205 has in large part supplanted grade 904L in applications.

Key Features of Stainless Steel 904L

The sections that follow provide descriptions of the flat-rolled product properties defined by ASTM B625.

The standards for other materials like bars, tubes, and pipes might not be the same.

Corrosion Protection

Grade 904L showcase super resistance to chlorine damage and warm seawater corrosion.

Heat Resistance

Stainless steels 904L with strong oxidation resistance are available. However, this grade loses structural balance at excessive temperatures, extensively above 400°C.

Welding

Stainless steels 904L can be welded using any traditional technique. Preheat and post-weld heat treatments are not needed for this grade.

Fabrication

High purity, low sulfur stainless steels in fabrication grade 904L are available. They can be use any standard methods. These can easily bent to a short radius in cold weather. Some of the major applications of grade 904L stainless steels include:

  • Electrostatic precipitators’ wiring
  • Components of an oil refinery
  • Equipment for cooling seawater
  • Plants for cleaning gas
  • Industries that process paper and pulp
  • Processing facilities for acetic, phosphoric, and sulfur acids.
