Stainless steel chain plate as a product that directly contacts with the materials transported, it must not only bear the tension and friction from the driving parts, but also bear the pressure from the materials. Today, we will explain why the stainless steel chain plate will crack.
The reason of stainless steel chain plate cracking is as follows
Stainless steel chain plate through professional grinding tools stamping forming a form of high-quality conveyor belt. In order to get this shape, the raw material needs to be punched by a special-shaped die, and it is difficult to release the residual stress after the rapid deformation of the material. In the process of use, under the action of external force and its own stress, the stainless steel chain plate may be corroded and cracked, thus failure.
At this time, the stainless steel chain plate is disconnected according to the normal crack. Therefore, the fracture surface of the parts failed due to stress corrosion cracking will include the characteristic area of stress corrosion cracking and the "dimple" area associated with the polymerization with slight defects. The formation and development of the pattern of stainless steel chain plate is roughly straight with the direction of tensile stress. The stress value which leads to stress corrosion cracking is much smaller than that required for data cracking in the absence of corrosive medium. From the microscopic point of view, the crack passing through the grain is called the transgranular crack, and the crack along the grain boundary is called the intergranular crack. When the stress corrosion cracking extends to a certain depth, this is the failure of the post stainless steel chain plate.
Stainless steel chain plate is often used in the transportation of glass products industry, food processing industry, dehydrated vegetables and frozen food.
