Titanium Screws for Bleach Corrosion Resistance

Q: We are using a bleach solution as part of a medical device application and seeing some rust/corrosion? Any ideas on a fastener material that will not corrode in bleach? Chemicals used are: 5.25% Sodium hypochlorite (or 10% bleach), 70% Isopropyl alcohol and Ammonium chloride

A: You might want to consider a titanium screw. Titanium fasteners will hold up to all those chemicals without any issue or rusting that you are currently experiencing with coated steel. The steel will always have a limited life and whenever you are depending on a plating it will be prone to failures.
