Grade 904L SS Sheets / Plates / Coils

Grade 904L is a superaustentic stainless stain that is made for moderate  huge corrosion resistance in a wide range of process environment. The grade is projected for use under simple corrosive conditions. It has been claim proved over many years and was initially developed to repel corrosion in dilute sulfuric acid. It is identical and approved for pressure vessel use in numerous countries. Actually, 904L is fully austenitic and is less complex to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904L has decent resistance to overall corrosion, mainly in sulfuric and phosphoric conditions.

Typical Composition:

Chromium: 19-23%
Nickel: 23-28%
Molybdenum: 4-5%
Copper: 1-2%
Manganese: 2% max
Silicon: 1% max
Carbon: 0.02% max
Phosphorous: 0.045% max
Sulfur: 0.035%
Iron: Balance

904L grade is useful in instrumentation & control tubing applications.

Typical Applications:

Utility scrubber assemblies
Heat exchangers
Acetic, sulphuric & phosphoric acid processing plants
Gas washing
Acid and fertilizer production equipment
Condenser tubes
Seawater cooling equipments

904L is usually used in the organic, pharmaceutical, oil and gas industries. Typical solicitations include tanks, valves, heat exchangers, flanges, and manifolds. The adding of copper to the composition of 904L assistances its rightness for apparatuses such as tanks and other products used in treatment sulphuric and phosphoric acid.
