Cl Stress Corrosion Cracking of Austenitic Stainless SteelNov 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. At higher temperatures of 250 to 300°C (480
Jan 01, 2013 · A new austenitic stainless steel grade, Sandvik Sanicro 25 (UNS S31035), has recently been developed for the purpose of A-USC  in collaboration with a number of different industrial partners within the Thermie- project in Europe, intended for use in super-heaters and reheaters in advanced ultra-supercritical boilers at temperatures up to
Effect of Cerium on the Austenitic Nucleation and Growth Feb 21, 2020 · The influence of small amounts of cerium on the solidification phenomena of S31254 high-Mo austenitic stainless steel was investigated by in situ observations and theoretical calculations. In situ observations indicate that cerium addition in molten steel can accelerate austenitic nucleation but inhibit primary austenite grain growth. The initial nucleation temperature occur 32.3 °C in
