[Analysis Case] Analysis of Metal Foreign Objects in Tubes
It is possible to estimate the material and type of metal foreign objects!!
We will introduce a case study of the analysis of metallic foreign objects present in a tube. The foreign object was collected, and morphological observation was conducted using SEM, followed by elemental analysis using the SEM-EPMA method, and semi-quantitative analysis of the detected elements was performed. ■ Information received from the customer regarding the occurrence of foreign objects - Situation of foreign object occurrence ⇒ Tube manufacturing - Material, size, and color of the foreign object ⇒ Metal, slightly less than 1 mm, rod-shaped, metallic luster - Expected content of the foreign object ⇒ Metal fragment - Other information ⇒ None in particular ■ Results Based on the elemental analysis results, the foreign object was determined to be stainless steel (SUS) of the Fe-Cr-Ni system. Furthermore, from the semi-quantitative analysis results, it was inferred to be austenitic SUS316 stainless steel. Stainless steel is widely used in various metal materials and components due to its excellent corrosion resistance.
