Nickel Distribution of Iron Blades
Nickel is an important alloying material in stainless steel because it enhances material performance and places the most important anti-rusting element in the finished material. In the production of stainless steel blades, nickel plays an important role in the process, and its distribution also directly affects its use performance.
The cutting performance of stainless steel blades is closely related to the right amount of nickel content. Generally speaking, the steel blades with high nickel content are better in cutting performance. The stainless steel blades with high nickel content can reduce the friction coefficient during the cutting process, so that the cutting edge is subjected to less compression force, which greatly improves the cutting sharpness of stainless steel blades.In addition, the small grain size of stainless steel blades is a necessary condition for its high hardness, and the small grain size can be kept stable by alloying with a small amount of nickel.
The production process of stainless steel blades requires the uniform and reasonable distribution of nickel, which in turn requires manual control or mechanical control.
In mechanical control, the number and size, as well as the segregation speed and distribution of nickel particles, are controlled by changing the spray distance of the electrostatic sprayer, setting different atomization pressures, increasing or decreasing the arc current, and controlling the spray distance, spray time, and powder amount, etc. Controlling the amount of each atomizer output and the total number of atomizers required.
The manual control method is mainly to apply a uniform and reasonable surface coating or spraying process to ensure that the nickel particles on the surface of the stainless steel blades are even and dense. In the manual spraying process, the operator manually adjusts the distance between the spray gun and the stainless steel blade to ensure that the stainless steel blade is evenly sprayed with nickel.
The uniformity of nickel distribution in stainless steel blades is mainly reflected in the uniformity of surface and internal composition of steel blades. The uniform distribution of nickel particles in steel blades can better maintain and reflect the properties of stainless steel.
Stainless steel blades with a variety of uses have different nickel distribution requirements. In general, stainless steel blades used for food-grade cutlery have higher requirements for nickel distribution than stainless steel blades used for ordinary ordinary tools, so as to better maintain the food cleanliness grade needed for use in food production.
