304 antibacterial stainless steel plate has beautiful surface and diverse use possibilities. Its corrosion resistance is as long-lasting as ordinary steel. 304 antibacterial stainless steel plate has good corrosion resistance and high strength, so it is more likely to be used as a thin plate. It is resistant to high temperature oxidation and has high strength, so It can resist fire and be processed at room temperature, that is, it can be easily plastic processed. Because no surface treatment is required, it is simple, easy to maintain and clean, and has high smoothness and good welding performance.
The main difference in chemical composition between 316 and 304 is that 316 contains Mo, and it is generally recognized that 316 has better corrosion resistance and is more resistant to corrosion than 304 in high temperature environments. Therefore, in high temperature environments, engineers generally choose parts made of 316 material. But as the saying goes, nothing should be taken for granted. In the concentrated sulfuric acid environment, no matter how high the temperature is, never use 316. We know that in order to prevent the thread from seizing under high temperature, a dark solid lubricant needs to be applied.
304 antibacterial stainless steel plate Due to the high yield point and high hardness of antibacterial stainless steel itself, cold work hardening effect is significant. When the 304 antibacterial stainless steel plate is bent, its characteristics are as follows: Because the thermal conductivity is worse than ordinary low carbon steel , the elongation rate Low, resulting in a large deformation force required. Compared with carbon steel , stainless steel sheets have a strong rebound tendency during bending. stainless steel sheets have a low elongation compared to carbon steel, so the bending angle of the workpiece during bending R should be greater than carbon steel, otherwise there is a possibility of cracks; due to the high hardness of the 304 antibacterial stainless steel plate, the cold work hardening effect is significant. Therefore, when selecting a bending tool, you should choose tool steel with a heat treatment hardness of more than 60HRC, and its surface is rough. The strength is an order of magnitude higher than that of carbon steel bending tools.
Based on the above characteristics, generally speaking: under unit size, the thicker the plate, the greater the bending force required, and as the plate thickness increases, the margin for bending force should be larger when selecting bending equipment; under unit size , the greater the tensile strength, the smaller the elongation, the greater the required bending force, and the larger the bending angle should be.
According to the actual situation, the expansion size of a curved workpiece is the sum of the right-angled sides minus two plate thicknesses, which can fully meet the design accuracy requirements. Calculating the expansion amount based on empirical formulas can simplify the calculation process and greatly improve production efficiency; the yield strength of the material The larger the , the greater the elastic recovery. In order to obtain a 90-degree angle for the bent part, the angle of the required press knife must be designed to be smaller. Compared with the 304 stainless steel plate with the same plate thickness as carbon steel, the bending angle is larger. Special attention should be paid to this, otherwise bending cracks will appear, which will affect the strength of the workpiece. Sometimes it occurs immediately when the drawn part is retracted from the punch, sometimes it occurs when the drawing deformation is first bumped or vibrated; sometimes it occurs after a period of storage or use after the drawing deformation. It only happens during the process.
