Salt Spray Test.The salt spray test is an accelerated laboratory test that provides a controlled corrosive environment to determine the corrosion resistance of stainless steels.It exposes components to a salt spray (fog) solution of 5 percent sodium chloride in a test chamber heated to 95 degrees F.Need justification to eliminate salt spray testing of 300 The salt spray test method in AMS 2700 is used to detect anodic surface contamination,including free iron,on corrosion resistant steel for a minimum of 2 hours.This seems to be a different purpose than salt spray testing for overall corrosion attack for a certain time of exposure as is required,which would be a customer requirement.Need justification to eliminate salt spray testing of 300 The salt spray test method in AMS 2700 is used to detect anodic surface contamination,including free iron,on corrosion resistant steel for a minimum of 2 hours.This seems to be a different purpose than salt spray testing for overall corrosion attack for a certain time of exposure as is required,which would be a customer requirement.

Oct 01,2017 ArticleSalt spray testing of stainless steels#0183;Stainless steels naturally corrosion-resistant metal alloys are auto-passivating,which means they spontaneously produce a passivation layer (a thin passive film) in oxidizing environments like air or moisture.The passivation layer is non-reactive it inhibits the electrochemical reactions that would normally take place between the base material and the environment.Comparative Analysis of Stainless Steel and Carbonmanufacturers now assign salt spray testing to stainless steel product; it is primarily intended for carbon steel parts.Stainless steel is generally tested in a humidity chamber without salt.In instances where exposure to chlorides is of paramount concern,salt spray testing is an acceptable method of test for stainless steel.Certification of salt spray performance of stainless steel The salt spray performance of a stainless steel flat rolled product is not solely dependent on chemical composition.Exposure to contaminants during fabrication of the strip and subsequent processing of the strip into parts can greatly affect the salt spray performance of a finished part.
