Through the comprehensive analysis, the result shows that crack failure reason is embrittlement of the austenite stainless steel at high temperature.
通过综合分析指出对流管发生失效的原因是奥氏体不锈钢长期在高温下工作引起的热脆化开裂。
Mechanism of reheat embrittlement and reheat crack is the same. Reheat embrittlement cannot be avoided by reducing stress.
再热裂纹与再热脆化的机理相同，两者同时发生，降低应力防止再热裂纹并不能防止再热脆化。
