Figure 4. S460NL fatigue specimens exposed to natural atmospheric conditions on the roof of the Experimental and Diagnostic Building Center at VŠB–TU Ostrava. The specimens were mounted on an outdoor exposure frame to simulate real environmental conditions. Plastic covers were used to protect the threaded ends of the specimens from corrosion . Typical specimens of steel S460NL for fatigue experiments without and with four various levels of corrosion are shown in Fig. 5 .

Figure 5. Examples of steel specimens for fatigue experiments without and with four various levels of corrosion. Reference; 3 (35°C) days; 6 (35°C) days; 6 (35°C) +3 (50°C) days specimens and specimen from natural exposure (from left to right).
