This set of block or scrap certified reference material of micro alloy steel, whose components covered all micro alloy steel types that have been studied or are being studied at home and abroad were developed with highly pure raw and processed materials through scientific smelting and forging process. The homogeneity of reference materials were studied with the samples selected from different positions of materials. The certified value and the extended uncertainty of 24 elements including vanadium, niobium, titanium and nitrogen were determined by 14 labs with abundant experiences in certification of reference materials. The linear investigation of the characterisation elements indicated that the relative coefficients of characterisation elements were above 0.99 except bismuth and calcium, and the efficient point for each element were no less than four.
