为什么公司采购的不锈钢锻件总是坏了呢？

为什么公司采购的不锈钢锻件总是坏了呢？

不锈钢锻件的质量问题很多，如在机械加工中出现裂纹，含碳量过高等。在实际工作中，若要判定不锈钢锻件半成品件、成品件或使用件的故障究竟是什么原因造成的并不是一件非常容易的事情。相对而言，半成品件或成品件出现的故障分析起来可能稍容易些，而对于使用件的故障或者失效原因的分析就要费些周折。在进行这些故障件的分析时首先应了解故障件的使用经历和制造经历，即要了解设计情况、选材情况、冷工艺情况、热工艺情况、受力情况、使用维护情况包括环境情况，只有对以上各项情况进行全面了解之后，并根据故障件的宏观、微观形貌特征，这些形貌特征在什么情况下出现，是否具有产生这种形貌特征的条件，并通过材质分析、力学性能分析、金相组织分析，配以电子显微镜、电子探针等一些高级手段，通过与各方面专业人员的学习、交流、分析，按照失效分析的程序得出故障件产生故障的真实原因，并能得知故障产生的原因是否为锻件质量问题。　　锻件质量问题产生的原因是多方面的，通过对锻件的宏观、微观分析，有时还要进行模拟试验，从而得出质量问题产生的原因究竟是锻造工艺本身还是其它影响因素(如原材料、热处理、表面处理或者试验本身的失误等)；是锻造工艺制定得不合理不完善还是工艺纪律不严格没有严肃认真地执行工艺，这些都只有在经过细致的研究分析之后才可做出结论。

当然了，就是因为有很多的不锈钢锻件质量都不过关，所以大家在购买的时候更要看清楚质量。
