ASTM A380 Test for Cleaning and Passivation of Stainless Steel

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM A380 testing. This standard exists to remove from new stainless steel parts, equipment and surface contaminants that may impair normal corrosion resistance, cause subsequent contamination of a particular grade of stainless steel or product contamination.

Cleaning accomplishes this by removing oils, waxes, and greases through a variety of methods, including solvent cleaning, steam degreasing, ultrasonic cleaning, and others. Cleaning helps to achieve the desired appearance as well as removing contaminants that can impair the metal's corrosion resistance.

It involves the removal of heavy, tightly adherent oxide films from descaling, hot forming, heat treatment, welding and other high temperature processes. However, because mill products are typically supplied in a descaling condition, this process is not usually required during equipment fabrication or systems assembly. It can be done by one or more methods when necessary.

For example, chemical descaling, also known as pickling, uses aqueous sulfuric acid or nitric and hydrofluoric acid, molten alkali or salt baths and various proprietary formulations to remove oxide films.

ASTM A380 details these three services in detail, detailing their acceptable methods for new stainless steel parts, equipment, and systems. The standard does not cover decontamination or cleaning of equipment or systems in service, or descaling and cleaning of materials in the mill.
