304 Stainless Steel Plate for Processing Characteristics

316 and 304 in the chemical composition of the most important difference is 316 Mo, and generally recognized 316 corrosion resistance better than 304 in high temperature environment, more resistant to corrosion. So in high temperature environment, engineers will generally use the 316 material parts. But the so-called things without absolute, in the concentrated sulfuric acid environment, and then do not use the high temperature 316, we know that in order to prevent the high temperature in the case of thread bite, need to apply a dark solid lubricant.

304 stainless steel itself due to the high yield point, high hardness, cold hardening effect is remarkable, 304 stainless steel plate bending characteristics are as follows: due to thermal conductivity than ordinary low carbon steel, low elongation, resulting in the required deformation of large; stainless steel sheet metal in the bending and carbon steel compared to a strong rebound tendency; stainless steel plate relative to the carbon steel due to low elongation, bending the workpiece bending angle R is greater than carbon steel, otherwise there may be cracks; 304 stainless steel plate hardness is high, cold hardening effect is significant Therefore, in the choice of bending tools to choose the heat treatment hardness should be more than 60HRC tool steel, the surface roughness than carbon steel bending tool an order of magnitude higher.

According to the above characteristics, in general: the greater the thickness of the plate, the greater the required bending force, and with the increase in plate thickness in the choice of bending equipment, the margin should be greater; , The greater the tensile strength, the smaller the elongation, the greater the required bending force, the greater the bending angle should be.

According to the actual situation, the expansion of a bending of the workpiece size of the right side of the addition of minus two thickness, fully meet the design accuracy requirements, according to the empirical formula to calculate the expansion of the calculation process can greatly simplify the production process; material yield strength , The greater the amount of elastic recovery, in order to obtain the angle of 90 degrees bending, the required angle of the knife to be designed smaller. Relative to the same thickness of carbon steel 304 stainless steel

Plate bending angle is large, which should pay special attention to otherwise there will be bending crack, affecting the workpiece strength. And sometimes in the indentation from the punch out immediately when the back, sometimes not in the deep deformation of the first hit or calm when the flu; sometimes in the deep deformation of the first by a period of time in the storage or in the application Process only attack.
