Analysis and preventive measures of stainless steel seamless pipe cold treatment cracks
Stainless steel seamless pipes are typically made of medium to high carbon and alloy steels. After quenching, some subcooled austenite may not fully transform into martensite, resulting in the presence of retained austenite. This retained austenite can negatively impact the pipe's performance. By further cooling below zero, the transformation of retained austenite into martensite is promoted, making cold treatment essentially an extension of quenching. However, the stresses from quenching at room temperature combined with those from sub-zero treatment can exceed the material’s strength limit, leading to cold treatment cracks.
