Corrosion resistance of Brass
- Thread starter Redpoint
- Start date
In general, the following materials, Al , cast iron, steel, brass and ferritic and martensitic stainless steel exhibit poor corrosion resistance in phosphoric acid.<br>
<br>
To be specific for 70-30 brass corrosion rate at 70 F 100% corrosive medium of phosphoric acid the corrosion rate is > 0.05 mpy (mil per year) which is very poor and unacceptable in metallurgical sense.<br>
<br>
Type 316 austenitic Stainless steel will be a choice for phosphoric acid environment . It can be used up to 85%conc. and temperature up to boiling point with little attack.<br>
<br>
