“…This fact has already been previously experimentally demonstrated by Kohl (9), who studied the effect of temperature on the initiation and crack propagation processes in MgClz solutions using a 19 Cr-9 Ni alloy loaded in uniaxial tension. The lowest stress corrosion crack growth rate and the maximum threshold value K that were found at room temperature in the solution of 5 n Hz SO4 + 0.5 n NaCl are therefore probably rather resulting from the effect of temperature than from the chemical composition and concentration of the test solution.…”

Stress corrosion crack velocity and stress corrosion threshold stress intensity have been measured for 18Cr-1 ONi-0,s Ti stainless steel in relation to environmental variations. These studies showed that both stage I and stage IIgrowth rate dependence on K are influenced by environmental variations. The chemical composition of the solution being tested, the corrosion-active components concentration and temperature that influence corrosion kinetics, all influence SCC susceptibility through their effects on overall film stability and localisation of corrosion. The influence of environmental factors on protective film stability was suggested to be an explanation for different values of stress corrosion threshold stress intensity found for different test conditions.

Kinds of crack‐producing corrosion and their significance for the availability of components of chemical plants. Interor transcrystalline cracks in metallic components of chemical plants can occur under the combined influence of mechanical stress and corrosion. Since they usually remain unrecognized before the occurrence of visible damage – leakage of a vessel or fracture of a structural part – such crack‐producing corrosion processes are greatly dreaded. Based on differences in the mechanism of the process of damage, one distinguishes two groups, i. e. stress corrosion cracking (SCC) and corrosion fatigue (CF). SCC stands for an interaction between local corrosion attack and quasi‐static tensile stresses (load‐ and/or residual stresses). CF means a combination of mechanical stresses differing in time and corrosion. Hydrogen induced SCC is a special kind of crack corrosion, initiated by atomic hydrogen absorbed in a metal. The paper describes the different systems of SCC and CF, the forms of failure, the parameters, and the possibilities of avoiding damages, especially emphasizing their significance in practice.

Die Ergebnisse der Prüfung der Spannungsrißkorrosion austenitischer nichtrostender Stähle in MgCl2‐Lösung sind empfindlich abhängig von der Art und der Durchführung der Prüfung. Die Prüfmethode, wie sie in der Forschungsanstalt der Schoeller‐Bleckmann Stahlwerke AG in Verwendung ist, wird besprochen und es wird der Einfluß verschiedener Einzelheiten der Versuchs‐durchführung aufgezeigt, wie die Vorbereitung der MgCl2‐Lösung, das Vorwärmen des Probengefäßes mit Wasser, der Oberflächenzustand der Probe, der Probendurchmesser, die Abdeckung des Probenschaftes, der Zeitpunkt der Lastaufgabe und die Potentialvorgabe. Am Beispiel der Spannungs‐, Konzentrations‐und Temperaturabhängigkeit der Standzeit wird gezeigt, daß die Versuchsdurchführung nicht nur die Standzeit, sondern auch das Ausmaß und die Art der genannten Abhängigkeiten verändern kann. Prüfergebnisse haben daher nur im Zusammenhang mit den genauen Prüfbedingungen ihren vollen Wert.
