It is mainly used in production welding of ferritic spheroidal cast iron with specific mechanical properties, such as ENGJS40018LT
Smut and Desmutting | Products Finishing
Feb 01, 2001 · Smut can be fairly readily removed in a desmutting or deoxidizing acid bath. This can be any one of numerous compounds, or mixtures, including nitric acid, sulfuric acid, chromic acid and more. There are also mixtures of ferric sulfate, hydrogen peroxide and other chemicals that are used effectively in desmutting baths.

Petroleum Diesel and Biodiesel Fuels Used in a Direct ...
The performance of a direct hydrocarbon phosphoric acid fuel cell, PAFC, was investigated using petroleum diesel, biodiesel, and nhexadecane as the fuels. We believe this is the first study of a fuel cell being operated with petroleum diesel as the fuel at the anode. Degradation in fuel cell performance was observed prior to reaching steady state.
Method for removing iron in the manufacture of phosphoric acid
Apr 11, 2016 · A phosphoric acid solution was prepared from rock with a high iron content in a conventional manner using a commercial chemical processing plant as shown in FIG. 1 but absent iron removal subsystem 100. The phosphoric acid solution was concentrated to 54% and clarified as shown in FIG. 1 by phosphoric acid evaporator 62 and clarifier 64.

Corrosion of Cast Irons – IspatGuru
Jun 28, 2016 · Graphite morphology can play an important role in SCC resistance in certain atmospheres. In oleum, flake graphite structures cause special problems. Acid tends to penetrate along graphite flakes and corrodes the iron matrix. The corrosion products formed build up pressure and eventually crack the cast iron.
