Alloy 904L is a multi-purpose material can be applied in many industrial :
1. Petroleum, petrochemical equipment, such as the reactor in petrochemical equipment.
2. Sulfuric acid storage and transportation equipment, such as heat exchanger.
3. Power plant flue gas desulphurization equipment, the main parts: the absorption tower, flue , stopping plate, internal part, spray system.
4. The scrubber and the fans in the organic acid treatment system.

Corrosion resistance
In general welding and heat treatment, there will not be carbide precipitation because of the carbon content is very low (0.020% maximum). This eliminates the intergranular corrosion after the
welding and heat treatment. Due to high nickel chromium molybdenum content, and copper element, so even if the 904L in reducing environments, such as in sulfuric acid and formic acid can be
deactivationcan be deactivation. High nickel content also has a lower corrosion rate in the activity state. In the range of 0 ~ 98% concentration pure sulfuric acid , 904L of the use of temperature
can be as high as 40. In the range of 0 ~ 85% concentration pure sulfuric acid, its corrosion resistance is very good. In the industrial phosphoric acid production of Wet method,the impurities are
strongly influence of corrosion.
