Abstract. The stress corrosion cracking (SCC) characteristics of ASTM A517 Grade F steel in liquid ammonia environments have been investigated. Acceleration of the cracking process was accomplished at 150 psig by the use of a dynamic slow strain rate testing procedure capable of producing cracking in as little as 24 hours.

Nov 02, 2020 · Oxygen level is another an important factor for Cl-SCC. If the oxygen level is in the 0.01 to 0.1 ppm range, aqueous solutions containing low to moderate levels of Cl-are less likely to crack an austenitic stainless steel. Note that the O 2 solubility in water at around 60°C is about 8 ppm and thus is often considered to be a contributing factor.
