ASTM A380 - Stainless Steel Passivation by Keystone

Passivation per ASTM A380 . Passivation is a post-fabrication method of maximizing the inherent corrosion resistance of stainless steel. Passivation is a process that removes exogenous iron or iron compounds from the surface of the stainless steel alloy. This process greatly reduces the formation rust on the surface of the workpiece. What is A380 testing?What is A380 testing?We offer ASTM A380 testing in the and the field to help you find contamination in new and refurbished vessels before they go into service. ASTM A380 includes information on cleaning, descaling, and passivating stainless steels, as well as the tests the can be applied to ensure your surface is contaminant-free.Stainless Steel Contamination Testing per ASTM A380

Pickling and Passivating Stainless Steel

The corrosion resistance of stainless steel is due to a 'passive', chromium-rich complex, oxide film that forms naturally on the surface of the steel. This is the normal condition for stainless steel surfaces and is known as the 'passive state' or 'passive condition'. Stainless steels will naturally self-passivate whenever a clean surface is stainless steel contamination testing per astm a380Stainless Steel Contamination Testing per ASTM A380We offer ASTM A380 testing in the and the field to help you find contamination in new and refurbished vessels before they go into service.
