ISO 3651-1 Determination of the Resistance of Stainless Steels to Intergranular Corrosion - Austenitic and Ferritic - Austenitic (Duplex) Stainless Steels - Corrosion Test in Nitric Acid Environment by Measuring Mass Loss (Huey Test)

EUROLAB laboratory provides testing and compliance services within the scope of ISO 3651-1 standard. This part of ISO 3651 specifies a method for determining the resistance to intergranular corrosion of austenitic and ferritic-austenitic (duplex) stainless steels in nitric acid environment by measuring mass loss (Huey test). It also specifies the purpose that can be assigned to the test.

ISO 3651-1 Determination of the Resistance of Stainless Steels to Intergranular Corrosion - Austenitic and Ferritic - Austenitic (Duplex) Stainless Steels - Corrosion Test in Nitric Acid Environment by Measuring Mass Loss (Huey Test)

The method is applicable only to austenitic and ferritic-austenitic (duplex) stainless steels supplied as rolled or forged products, pipes and castings and intended for use in a strongly oxidizing medium (for example, relatively concentrated nitric acid). In general, the Huey test should not be used for molybdenum containing grades unless the material being tested is used in nitric acid service.

It is important to note that the result of the corrosion test is strictly valid only for the corrosive medium used in the test. It provides a basis for estimating resistance to intergranular corrosion, but cannot be used to check resistance to other forms of corrosion (general corrosion, pitting, stress corrosion, etc.). The user must adapt the specified corrosion test to the use to be made of the alloy. In no case should this test be considered an absolute criterion of the quality of the alloy.
