304 stainless steel plate for processing characteristics

304 stainless steel plate surface appearance and use of a variety of possibilities, corrosion resistance, durable than ordinary steel, 304 stainless steel plate corrosion resistance is high, therefore, the possibility of using sheet, high temperature oxidation and high strength, so can resist
Fire prevention treatment at room temperature, that is, easy plastic processing, because there is no surface treatment, so simple, simple maintenance, clean completion, high welding performance.
The most important difference between 316 and 304 in chemical composition is 316 Mo, and it is generally believed that the corrosion resistance of 316 in high temperature environment is better than that of 304 and more corrosion resistance.
Therefore, engineers usually use 316 of the material parts in high temperature environment. But the so-
Called nothing absolute, in the concentrated sulfuric acid environment, and then do not use high temperature 316, we know that in order to prevent the high temperature of the thread bite, it is necessary to apply dark solid lubricant.
304 stainless steel itself has high yield point, high hardness and remarkable cold hardening effect. the bending properties of 304 stainless steel plates are as follows: due to the high thermal conductivity and low elongation, the required deformation is large;
Stainless steel plate has a strong rebound tendency compared with carbon steel when bending;
The bending angle R of the curved workpiece is greater than that of carbon steel due to the low elongation of stainless steel plates, otherwise cracks may occur; 2.
The 304 stainless steel plate has high hardness and significant cold hardening effect. Therefore, when selecting the bending tool, the selected tool steel with heat treatment hardness should be greater than 60HRC, and the surface roughness is one order of magnitude higher than the carbon steel bending tool.
According to the above features, generally speaking: the greater the thickness of the plate, the greater the bending force required, and with the increase of the thickness of the plate, the profit margin should be greater when choosing the bending equipment;
, The greater the tensile strength, the smaller the elongation, the greater the bending force required, the greater the bending angle should be.
According to the actual situation, under the condition of adding and subtracting two thicknesses on the right side of the workpiece size, the bending is expanded to fully meet the design accuracy requirements, and the calculation process is expanded according to the empirical formula, which can greatly simplify the production process; 2.
The greater the yield strength of the material, the greater the amount of elastic recovery, in order to obtain the angle of 90 degree bending, the angle of the knife needs to be designed smaller.
The bending angle of carbon steel 304 stainless steel sheet with the same thickness is large, special attention should be paid, otherwise bending cracks will occur, affecting the strength of the workpiece.
And sometimes it is right back when it comes out from the Dent of the punch, sometimes there is no deep deformation when it is just hit, or calm down when the flu;
Sometimes when deep deformation is first stored or only attacked during the application for a period of time.
