SAF™ 2205 — Alleima
The high resistance of SAF 2205™ is shown in the figure by the fact that very high stresses, about 1.1 times the 0.2% proof strength, are required to induce stress corrosion cracking. The resistance of welded joints is slightly lower. The ferritic chromium steel ASTM 410 fails at considerably lower stress. Figure 9.

Improving the Corrosion Resistance of Duplex …
The effect of pickling in improving the corrosion resistance of duplex stainless steel welds was discussed earlier. In typical service in seawater the risk of corrosion is crevice corrosion for parent metal, but pitting for welds. The graph shows that at 1,000 mV SCE the CPT is the same as the CCT, but they diverge at lower potentials.
