What are the characteristics of 304 stainless steel plate bending processing?

304 stainless steel plate surface is beautiful and the possibility of use is diversified, good corrosion resistance, durable than ordinary steel, 304 stainless steel plate has good corrosion resistance and high strength, so the possibility of sheet use is high, high temperature oxidation resistance and high strength, so it can resist fire at room temperature processing, that is, easy plastic processing, because there is no need for surface treatment, so it is simple, simple and clean, high finish and good welding performance.

The main difference between 316 and 304 in chemical composition 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 environment, engineers will generally choose 316 material parts.

304 due to the high yield point of stainless steel itself, high hardness, cold hardening effect is significant,304 stainless steel plate bending its characteristics are as follows: due to poor thermal conductivity than ordinary low carbon steel, low elongation, resulting in large deformation force; Stainless steel sheet has a strong springback tendency compared with carbon steel when bending. Stainless steel plate relative to carbon steel due to low elongation, bending workpiece bending Angle R is greater than carbon steel, otherwise there is the possibility of crack; Due to the high hardness of 304 stainless steel plate, cold hardening effect is significant so in the selection of bending tools to choose heat treatment hardness should reach more than 60HRC tool steel, its surface roughness is an order of magnitude higher than the carbon steel bending tool.

According to the above characteristics, in general: unit size, the thicker the plate, the greater the required bending force, and with the increase in the thickness of the plate in the selection of bending equipment bending force margin should be larger; Unit size, the greater the tensile strength, the smaller the elongation, the greater the required bending force, bending Angle should be larger.
