430 antibacterial stainless steel cladding knife and preparation method thereof

Abstract

The invention discloses a 430 antibacterial stainless steel cladding knife and a preparation method thereof. The 430 antibacterial stainless steel cladding knife comprises the following chemical components in percentage by weight: less than or equal to 0.12% of C, less than or equal to 1% of Si, less than or equal to 1% of Mn, less than or equal to 0.04% of P, less than or equal to 0.03% of S, 16%-18% of Cr, 1%-3.5% of Cu, less than or equal to 2.5% of Mo, less than or equal to 0.035% of N, larger than or equal to 0.03% and less than or equal to 0.06% of C+N, larger than or equal to 0.04% andless than or equal to 0.14% of Ti+Nb+V, one or more of following alloy elements of Ti, Nb, Mo, V, Zr, Sn and Sc and the balance Fe and impurities, wherein the percent of each of Ti, Nb, Mo, V, Zr, Snand Sc is less than or equal to 1%. The comprehensive performance of the 430 antibacterial stainless steel cladding knife prepared through the method far exceeds that of a traditional martensitic steel knife, the problems that the traditional knife is healthy and safe in food contact, permanently resistant to corrosion and rust, sharp and durable are solved, and on the basis of the 430 antibacterial stainless steel knife, the laser cladding technology is used for improving the wear resistance and the sharpness of a finished cutting edge.

Description

technical field [0001] The invention relates to the technical field of knives, in particular to a 430 antibacterial stainless steel cladding knife and a preparation method thereof. Background technique [0002] With the progress of society and the improvement of people's living standards, people pay more and more attention to the living environment and quality of life, but microorganisms invade people all the time, and the spread and spread of harmful bacteria seriously threaten people's health.
