Zusammenfassung:The invention discloses an analysis and calibration method for stainless steel chromium and nickel elements. The method comprises the steps that according to actual content ranges of element components of chromium and nickel in the stainless steel production, the standard sample preparing process technology development is carried out, and a standard sample suitable for sample detection of the stainless steel production is independently developed; a standard curve analysis and calibration technology of the stainless steel chromium and nickel elements is concluded, and an element interference calibration mode of a stainless steel standard curve is determined through experiments; a more scientific accuracy measurement method is adopted, accuracy test of the measurement method is conducted on the curve according to a high content section, an intermediate content section and a low content section, the method of using a high-carbon stainless steel control sample to replace a low-carbon control sample purchased on the market to control a stainless steel crude molten steel sample is adopted, comparison is conducted on data obtained through the method and those obtained through a classical chemical method, and the result is satisfactory. By means of the analysis and calibration method for the stainless steel chromium and nickel elements, the analysis accuracy of the stainless steel chromium and nickel elements is superior to that of GB11170-2008 (r).
