对某砖窑不锈钢吊钩进行了失效分析，确定了其失效机理。收集的证据表明，不锈钢钩的化学成分符合304不锈钢的标准要求。金相检验表明，不锈钢钩在非损伤区域的显微组织正常。但是，在损伤材料中发现了严重的铬偏析，这可能是由于在高温下形成第二相造成的。这大大降低了材料的耐腐蚀性。结果表明，氧和硫等腐蚀元素在腐蚀过程中起主要作用。因此，不锈钢钩的失效是由于铬偏析和包括氧和硫在内的腐蚀性元素的存在引起的腐蚀引起的。
Failure analysis was carried out on the stainless steel hooks in a brick kiln to confirm its failure mechanism. The collected evidence indicated that chemical composition of the stainless steel hook was consistent with the standard requirements for 304 stainless steel. The metallographic test showed that the microstructure of the stainless steel hook in the non-damaged areas was normal. However, serious chromium segregation which might be caused by secondary phase formation at the high temperature was found in the damaged material. This dramatically reduced the corrosion resistance of the material. The corrosion elements such as oxygen and sulfur were found playing a major role in the corrosion process. Thus, the failure of the stainless steel hook was induced by corrosion due to the chromium segregation and the existence of corrosive elements including oxygen and sulfur.
