Stress Relaxation Cracking: The Silent Threat in High-Temperature Stainless Steel Systems

Stress Relaxation Cracking (SRC) remains one of the least understood, yet most costly damage mechanisms in high-temperature process industries. It is often misdiagnosed, overlooked during inspection, or confused with other forms of intergranular cracking. Recent work by Sequence Computational Engineering sheds light on the mechanisms driving SRC in austenitic stainless steels and how material behaviour under stress and temperature leads to long-term failure.
