How to distinguish the quality of stainless steel angle bar

1. Fake and inferior stainless steel angle bar products contain many residues, the density of the steel is too small, and the general specification deviation is relatively serious. If there is no micrometer, it can be weighed and checked. 　　

2. The surface layer of fake and inferior stainless steel angle bar is very prone to scratches. It is because the production equipment is simple and easy to cause burrs and other scratches on the surface of the stainless steel plate. Deep scratches will continue to reduce the compressive strength of the angle bar. 　　

3. Fake and inferior stainless steel angle bar has no metallic texture, and the cold rolling temperature of fake and inferior raw materials is not standardized. Cold rolling cannot be carried out in accordance with the prescribed martensitic area. Of course, the characteristics of the angle steel cannot be qualified. 

4. High-quality stainless steel angle bar with well-proportioned composition, high tonnage of the cold shear, smooth and tidy cutting head inner hole, while counterfeit and inferior angle steel materials are weak, and the cutting head inner hole often has unevenness and dullness.  

5. The cross-section of the fake stainless steel angle bar is oval. Some manufacturers save raw materials, and the reduction of the first two passes of the finished product roll is too large, which will not only greatly reduce the compressive strength of the steel, but also not fit the size. Specifications. 　　

6. Because the manufacturing equipment is simple, the fake and inferior stainless steel angle bar materials are uneven, and there are many residues, and the surface layer is easy to cause scabs.
