ASTM A967 and AMS 2700 Standards for Passivation

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 …
