What are the common problems of fake Angle steel?

1. shoddy stainless steel Angle steel products contain more residue, the density of steel is small, and the general specification deviation is more serious, in the absence of a micrometer, it can be carried out weighing verification.

2. shoddy stainless steel Angle surface is very easy to scratch, it is because the production and manufacturing equipment is simple, easy to cause rough edge and other scratches stainless steel plate surface, deep scratch will continue to reduce the compressive strength of the Angle steel.

3. shoddy stainless steel Angle without metal texture, fake and shoddy raw materials cold rolling temperature is not standardized, can not be carried out in accordance with the provisions of the martensitic area cold rolling, of course, the characteristics of Angle steel can not be qualified.
