When we process stainless steel plates, we generally use mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve mirror stone luster according to the complexity of stainless steel products and user requirements. The advantages and disadvantages of these three methods are described below:
The heat treatment of stainless steel strip is to eliminate the work hardening after cold rolling, so that the finished stainless steel strip can achieve the specified mechanical properties. In the production of stainless steel strip, the commonly used heat treatment methods are as follows:
1. There is an identification liquid for stainless steel strips on the market, and you can know which type of stainless steel it is by detecting the nickel content in the stainless steel strip. 2. Magnetic identification of 304 stainless steel strip, generally the larger magnetic is 2 series stainless steel strip, non-magnetic or weaker magnetic is 3 series stainless steel strip (but these two methods can not clearly determine whether it is 304 stainless steel).
201 stainless steel strip can be used to produce all kinds of watch cases, strap bottom backs, decorative tubes, industrial tubes, and some shallow stretched products. Because 201 stainless steel strip has average anti-rust ability, 201 stainless steel strip is mainly used in civil industries that are not very demanding. Of course, 201 stainless steel strip is also often used in field open-air machines in the chemical, coal, and petroleum industries with high requirements for grain boundary corrosion, heat-resistant parts of building materials and parts with difficulty in heat treatment.
After processing, 310S stainless steel strip will be polished, polished and other operations, which can not only make the surface of 310S stainless steel strip bright, but also improve its quality. Let's share the polishing performance of 310S stainless steel strip. First, dry grinding and drawing
The relationship between the physical properties of stainless steel strip and temperature (1) Specific heat capacity With the change of temperature, the specific heat capacity will also change, but once the metal structure changes or precipitates during the temperature change of the stainless steel strip, the specific heat capacity will change significantly.
