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.
4 load frames (12 specimen): 0-20 kN and 1 load frame
(3 specimen): 0 – 100 kN, all constant load controlled
Tensile samples – length of max. 180 mm
- ASTM G 44 – 94
- DIN 50908
