Resumen
This work presents a comparison of Temperature-Time-Sensitization TTS diagrams obtained by Huey and modified Strauss standard, for detecting susceptibility to intergranular attack. The difference between these tests is the use of a strong or a slightly smooth oxidizing electrolyte. The diagrams obtained are different and if a sample tested by modified Strauss is sensitized, then it will be sensitized in the Huey test, but the contrary is not always true. This difference is because a sensitized sample has to have a continuous band lacking in chromium along the grain boundary in order to be sensitized in the modified Strauss test. This condition is not necessary in the Huey test.
