Answer :
Final answer:
Type 304L Stainless Steel is satisfactory for a phosphoric acid concentration of 100% up to 150º F. Beyond this temperature and up to 225º F, Type 321 Stainless Steel is required.
Explanation:
Type 304L SS (Stainless Steel) is satisfactory for phosphoric acid concentration of 100% up to about 150º F. This implies that at temperatures of 150 degrees Fahrenheit and below, 304L stainless steel will provide satisfactory resistance to the corrosive effects of 100% phosphoric acid. In contrast, if the temperature goes beyond 150º F and up to 225º F, a more heat-resistant type of stainless steel, Type 321, is recommended. This is because the enhanced high-temperature properties of Type 321 provide better resistance to the corrosive properties of phosphoric acid at these higher temperatures.
