METAL ANALYSIS METHOD AND METAL ANALYSIS DEVICE FOR STAINLESS STEEL

摘要

The present invention relates to a metal component analysis method for stainless steel and a metal component analysis device for stainless steel which can accurately and reliably analyze a stainless steel grade by a multi-analysis process for stainless steel among nonferrous metals. According to the present invention, the metal component analysis method for stainless steel comprises: an effective distance measurement step of calculating and notifying an analytic effective distance for a stainless steel metal to be analyzed; a corroding step of spraying an oxidizing material to corrode the stainless steel metal to be analyzed at the notified effective distance to corrode the stainless steel metal; a metal identifying step of deriving an analysis factor from the corroded stainless steel metal; a steel grade analysis step of analyzing a stainless steel grade based on at least one of a corrosion degree and a crystal structure for the corroded metal; and a data storage/display step of storing and displaying the stainless steel grade analyzed in the steel grade analysis step.
