Manufacture Of Stainless Steel Trash Can

Stainless steel trash can is widely used in house, shopping malls, hotels, office buildings and other indoor places. It has the effect of cleaning and decoration, and has the advantages of the material. Even if it is placed in the bathroom and other wet places, it is not rusty and durable. Now let us have a deep understanding of the process performance and see how we process stainless steel trash can.

The common stainless steel trash cans in the market are made of 201, 410, 430, 304 austenitic stainless steel. Austenitic stainless steel is non-magnetic or weakly magnetic, but after cold working, the microstructure also transforms into martensite. The greater the cold working, the more martensite transformation, the greater the magnetic properties of the steel. Some parts of stainless steel trash cans, such as the body and the lid, are formed by stamping, with large deformation force and elastic rebound. Therefore, in order to ensure the accuracy of stamping size and shape requirements, sometimes it is necessary to increase the rest, correction and necessary heat treatment. The yield strength of different products is very different. Therefore, we pay special attention to the load capacity of processing equipment in the process of shearing and forming stainless steel trash cans, to ensure the quality of the outer can.

How to make stainless steel trash can

Because the phenomenon of work hardening of stainless steel is very strong, it is easy to cause wrinkles in the process of drawing. Normally, the intermediate annealing should be carried out after each drawing. For the drawing parts with large deformation, the heat treatment to eliminate the internal residual stress should be carried out immediately after the final drawing, otherwise the drawing parts will produce cracks, which is the reason for the cracks of the defective stainless steel waste bin. The specification of heat treatment to remove internal stress is heating temperature 350 ~ 450 ℃, and then holding for 1 ~ 3 h at the above temperature; the hot drawing method can reduce work hardening and internal residual stress of the material, improve the tensile deformation ratio and reduce the tensile coefficient. For drawing stainless steel trash can parts with complex shape, we choose more advanced hydraulic press, hydraulic press and other equipment to deform it under low drawing speed to get better effect.
