不锈钢堆焊层中的铁素体含量对其力学性能、耐腐蚀性能和加工性能等都有很大影响，准确测定其铁素体含量至关重要。 磁性法和化学法是测定不锈钢堆焊层中铁素体数的两个基本方法。
The ferrite content in stainless steel surfacing layer has a great
influence on its mechanical properties, corrosion resistance and
processability, so it is very important to accurately determine the
ferrite content. Magnetic method and chemical method are two basic
methods to determine Ferrite Number in stainless steel surfacing layer.
研究缺失
Lack of research
目前的研究方向主要集中于磁性法和化学法测定铁素体数的原理，以及如何根据检测对象选择合适的铁素体含量测定方法，还有研究保定平面设计培训 保定室内设计培训 保定空调移机 保定太阳能维修 保定厨房排烟 雄安管道通风 焊接工艺参数和焊后热处理对铁素体含量的影响规律，但是很少有试样机加工对最终铁素体含量测定结果影响方面的研究。
At present, the research direction mainly focuses on the principle of
Ferrite Number Determination by magnetic method and chemical method, and
how to select the appropriate ferrite content determination method
according to the detection object, as well as the influence of welding
process parameters and post weld heat treatment on ferrite content, but
there is little research on the influence of sample machining on the
final ferrite content determination results.
