304 stainless steel plate surface is beautiful and the possibility to use diversification, corrosion resistant performance is good, than ordinary steel long durable 304 stainless steel corrosion resistance is good High strength, and therefore the possibility of using big plate, high temperature oxidation resistance and high strength, thus able to fight a fire Room temperature processing, namely easy to plastic processing, because need not surface treatment, so simple, simple maintenance, cleaning, high degree of finish Good welding performance.

　　316 and 304 on the chemical composition of the main difference is that contains 316 Mo, and generally accepted, the 316 has better corrosion resistance, more than 304 under the environment of high temperature corrosion resistance. So under the environment of high temperature, 316 engineers typically select material components. But no absolute, the so-called things under the environment of sulfuric acid, high temperature also don't use 316 again, we know that in order to prevent thread below high temperature circumstance bite dead, need to apply a black solid lubricant.

　　With 304 stainless steel itself high yield point, high hardness, cold work hardening effect significantly, 304 stainless steel plate bending its characteristics as follows: because of poor thermal conductivity than normal low carbon steel, low elongation, lead to the deformation force; Stainless steel sheet metal bending with carbon steel compared with strong springback tendency; Stainless steel plate relative to the carbon steel because of the low elongation, artifacts when bending corner R than carbon steel, or you may appear crack; Due to the high hardness of 304 stainless steel plate, cold work hardening effect significantly so when choosing bending tool to choose heat treatment hardness should reach more than 60 HRC tool steel, the surface roughness is an order of magnitude higher than carbon steel bending tools.

　　According to the above features, in general: unit size, the plate is thicker, the bending force, and with increase of thickness in choosing bending force of bending equipment allowance should be bigger; Unit size, the larger the tensile strength, elongation rate is smaller, the required bending force is larger, fold the corners should be bigger.

　　According to the actual situation, the size of workpiece bend for right side up minus two thickness, can completely meet the design accuracy requirement, according to the empirical formula computation quantity can simplify the calculation process is greatly increased production efficiency; The greater the yield strength of material, the greater the amount of elastic recovery, in order to obtain the bending of a 90 - degree Angle, the smaller the pressure cutter Angle is needed for design. Relative to the carbon steel plate thickness of 304 stainless steel plate bending Angle is bigger, it should pay special attention to, can appear otherwise bending crack affect the intensity of artifacts.
