Please provide suggestions – selection of stainless steel in special cases
Thread Content
Environment in which the workpiece is located: 1. In contact with organic acids (including citric acid), at low concentrations; the overall environment of the solution is that of a food product. 2. Temperature ranges from 80 to 100 degrees Celsius. Which stainless steel grade can provide the best corrosion resistance?
Various organic acids have different corrosive effects on stainless steel; for example, austenitic stainless steel exhibits good corrosion resistance to acetic acid and formic acid, but it is not resistant to oxalic acid at higher temperatures. As a precaution, using 316L or 317L allows for safer use in organic acid environments.
