AASHTO T 372M/T 372-17 (2021) is a standard method of testing the sensitivity of stainless steel to intergranular attack. The test evaluates the potential for the formation of a detrimental intermetallic phase in duplex stainless steel, as well as the susceptibility of austenitic or ferritic stainless steel to intergranular attack. The purpose of this test is to identify any potentially detrimental effects that could reduce the functional life of the stainless steel.

It is important to note that these tests do not estimate the service life of stainless steel products embedded in concrete. Instead, they specifically focus on assessing the sensitivity of the stainless steel to certain types of corrosion. This standard provides guidelines and procedures for conducting the test, ensuring consistent and accurate results.
