Web7 sep. 2009 · The occurrence of stress corrosion cracking above 120°F (49°C) is still likely and must be carefully considered when selecting material. The cracks are usually non-branching and fast growing, and are more often transgranular (through the grains) rather than intergranular (through the grain boundaries). WebStress-oriented hydrogen-induced cracking Hydrogen-induced craking Galvanically induced hydrogen stress cracking. How to select material. Steel materials that selected or qualified using NACE MR0175/ISO 15156 are resistant to cracking in defined H2S-Containing environments in oil and gas production, but are not nesessarily immune …
