This part of ISO 3651 specifies a method for the determination of the resistance to intergranular
corrosion of austenitic and ferritic-austenitic (duplex) stainless steels in a nitric acid medium by
measurement of the loss in mass (Huey test). It also specifies the purpose which may be assigned to
the test.
The method is applicable only to austenitic and ferritic-austenitic (duplex) stainless steels supplied in the
form of rolled or forged products, tubes and cast products 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
grades containing molybdenum unless the material tested is to be used in nitric acid service.
NOTE ¿ It is important to note that the result of the corrosion test is only strictly valid for the corrosive medium used in the
test. It constitutes a basis for estimating the resistance to intergranular corrosion but may not be used to check resistance to
other forms of corrosion (general corrosion, pitting, stress corrosion, etc.). It is necessary for the user to adapt the specified
corrosion test to the use which will be made of the alloy. This test should, in no case, be considered as an absolute criterion of
the quality of the alloy.
