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 (uniform corrosion, pitting, stress corrosion, etc.). It is necessary for user to adapt the specified corrosion test to the use which will be made of the steels. This test should, in no case, be considered as an absolute criterion of the quality of the metal.
