Stress Corrosion Cracking

Stress corrosion resistance under tensile loading

The resist­ance of metals and their welds to stress corro­sion crack­ing is determ­ined at room temper­at­ure with the help of selec­ted media, prefer­ably with 3.5 percent sodium chlor­ide solu­tion.

The meas­ure­ment is performed under static tensile load­ing (e.g. 75% of the Rp0.2 yield strength) and altern­ate immer­sion treat­ment over a period of 30 days or until the occur­rence of a frac­ture.

As a result, life­time tables and metal­lo­graphic exam­in­a­tion data are provided.
