Preparation method of high-carbon stainless steel standard sample

The invention discloses a preparation method of a high-carbon stainless steel standard sample, belonging to the field of detection of metallurgical samples. The preparation method disclosed by the invention comprises the steps of designing a casting mould, baking the casting mould and a steel ladle, selecting components, controlling the process of a casting process, demoulding, detecting physical performances, processing the sample, detecting the homogeneity of chemical components, carrying out deterministic analysis and determining effective height. The physical performances, the structural state, the component range and the homogeneity of the standard sample prepared by the invention can be satisfied; furthermore, the preparation cost is reduced; the sampling number is increased; at least 100 standard samples can be prepared every time; the number is above 20 times of that of die casting sampling; the preparation number can satisfy current production requirements; and thus, the standard sample preparation process has very high practical value and great popularization value in other matter test rooms.
