With the decrease of the thickness of cold rolling, the size of carbide decreased, and the number of large particles of carbide decreased. However, carbides with particle size greater than 1pm can be observed in the samples with different cold-rolled thickness, which will have adverse effects on the heat treatment and final properties of the materials. The decrease of the thickness of cold rolling will not only reduce the average particle size of carbide, but also produce new and finer carbides, even nano carbides. The amount of carbide increases with the increase of cold rolling down rate, when the cold milk down rate is no more than 70% (that is, the thickness of cold rolling is no more than 0). When 9m m) the amount of carbide increased slowly, but when the cold rolling down rate was greater than 70%, the amount of carbide increased rapidly. With the increase of the compression rate of the cold emulsion, the crystal defects such as vacancy, dislocation density and deformation subcrystal in the material were significantly increased.
Warehouse shelf accessories, (Warehouse racking parts), surface chrome will enhance the strength of stainless steel, good appearance effect, corrosion resistance; the connecting rod of the accessories in the warehouse rack is S-shaped for easy connection with other accessories.
