ASTM A967. General industries use this standard to describe and control the passivation of stainless steel. Passivation is a process of making stainless steel more stainless than it would be if left alone. It is based on using an acid (nitric or citric) under highly controlled conditions to remove free iron particles from the surface and to help form a metal oxide …
A citric acid passivation bath also takes far less time than nitric acid, speeding up the cleaning process considerably. However, for all these benefits, citric acid passivation is considerably more expensive, which is why many choose nitric acid to keep costs down. ASTM A967 details five different citric acid passivation methods: Citric 1: 4 ...
