Abstract:After introducing the development of knife and scissor materials at home and abroad, the chemical composition of 4Cr10Si2 steel is designed according to the steel alloying principle and Schaeffler diagram. Then 4Cr10Si2 steel sheet with the thickness of 6 mm is prepared. After the tests of hardness, microstructure, tensile property and EBSD, etc., heat treatment test of the steel sheet is carried out and the heat treatment parameters of making kitchen knives and scissors are confirmed. Then, after the bending strength and resistance electrochemical corrosion tests by using the samples treated with optimum heat treatment process, the steel is made into kitchen knives. The testing and trial show that 4Cr10Si2 steel has better performance than 4Cr13 except slightly lower Ecorr and Icorr.
