What factors affect the surface quality of sus 309s stainless steel plate?

What are the factors that affect the surface quality of sus 309s stainless steel plate? ? How much do you know about this problem?

1. The impact of the production environment. After a long period of processing, a lot of oil, carbon black, dust and other debris will also accumulate on the convection plate and the stove. If it is not cleaned in time, it will also fall on the surface of the stainless steel plate. In the production process, if it is processed into stainless steel pipes or other stainless steel profiles in a place contaminated by stainless steel plates, it will cause great damage to the stainless steel.

2. During the rolling process, due to high temperature, the surface of the stainless steel will be carbonized. If it cannot be removed in time, it will accumulate on the surface of the 309s stainless steel plate, and indentation will be formed after rolling.

3. Seasons change. Because of the thermal expansion and contraction of steel, the surface of stainless steel will be affected by the outside temperature when it cools naturally.
