Can You Use Stainless Steel Screws in Aluminum? | Hunker

Galvanic corrosion occurs when an electrically conductive liquid, such as water, connects the anode -- aluminum -- with the cathode -- stainless steel. Because the anode, or aluminum, corrodes quickly in comparison to the stainless steel, using aluminum screws in stainless steel would quickly weaken the structure as the aluminum degrades.

304 vs 316 Stainless Steel | Metal Casting Blog

304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.

Chloride stress corrosion cracking in austenitic stainless ...

Chloride stress corrosion cracking (CLSCC) is one the most common reasons why austenitic stainless steel pipework and vessels deteriorate in the chemical processing and petrochemical industries. Deterioration by CLSCC can lead to failures that have the potential to release stored energy and/or hazardous substances.
