Using Alconox passivation solution to protect stainless steel parts from corrosion
Passivation is the process of forming a passive layer of chromium oxide on the surface of stainless steel to protect it from corrosion. This is done by adding a chemical that removes free iron and allows chromium oxide to form. The reference for passivation of stainless steel is ASTM A967. See the Critical Cleaning Procedures section of this guide for passivation tests.
CITRANOX and CITRAJET passivation solution applications—safety, efficacy and ease of use
Citranox – Phosphate free, concentrated cleaner and metal brightener for high performance removal of metal oxides, scale, salts and inorganic residues in manual and ultrasonic cleaning.
Citrajet – Low foaming, phosphate-free, concentrated, liquid cleaner and metal brightener for high peformance removal of metal oxides, scales, salts and inorganic residues in labware washers, parts washers, power-spray systems and manual and ultrasonic cleaning.
