904L Valve


904L is a high-alloy austenitic stainless steel with low carbon content. Due to the combination of relatively high contents of chromium, nickel, molybdenum and copper, 904L has good resistance to severe corrosion, particularly in sulfuric and phosphoric conditions.

Industrial Processes Applications:

904L excels in many industrial processes. The following are some of the environments which 904L  is fully resistant.

  • • Dilute sulfuric acid                                      • Phosphoric acid
  • • Organic acids                                             • Acetic acid
  • • Formic acid                                                 • Hydrochloric acid at low temperature
  • • Neutral medium chlorine ion


Valve Applications:

904L valves serve many different applications in these industries:

• Chemical

• Metullurgy

• Desalination

• Pulp & Paper
