Method for detecting chemical components of metal material

The invention relates to the technical field of metal detection, discloses a method for detecting chemical components of a metal material, and aims to solve the problems that existing detection methods are difficult to accurately measure the contents of cobalt, chromium and carbon on the metal material, whether the current contents of cobalt, chromium and carbon exceed standards cannot be known, and the existing detection methods mostly need to add HF, so that the detection efficiency is high. The method comprises the following steps: S1, drying a to-be-detected metal material in a vacuum oven at 95-115 DEG C for 1.5 hours, taking out the metal material, adding a sodium hydroxide solution into a transparent container, adding the metal material into the sodium hydroxide solution, standing for 5-10 minutes, and observing whether the sodium hydroxide solution is changed or not. According to the detection method, light absorption values and working curves are compared and analyzed one by one, the multi-level area
