Stainless steel wire drawing board surface treatment and size
The usual stainless steel surface is usually smooth and matt. Matte stainless steel is made of brushed wire. Will the rust resistance of stainless steel be reduced?
At present, most of the stainless steel used for decoration needs to be brushed. Wire drawing is a deep surface treatment method after pickling and passivation of stainless steel surface. The surface becomes brighter and more reflective. It is generally believed that the pickling passivated surface is a good corrosion protection surface for stainless steel. Is stainless steel brushed finish easier to rust than no brushed finish?
The corrosion resistance of the stainless steel pipe after drawing is worse than that of the stainless steel pipe without drawing, because the drawing will destroy the surface composition and chromium content of the stainless steel. The reason for the strong corrosion resistance of stainless steel mainly depends on the content of chromium. If the chrome is damaged, its corrosion resistance is weakened, so pulling is more likely to rust than not pulling.
The corrosion resistance of stainless steel wire drawing sheet is mainly due to its content of nickel and chromium. Nickel is the main corrosion-resistant element, while chromium forms a smooth protective film on the surface of the stainless steel wire drawing sheet to protect it from corrosion. After drawing, the chromium element on the surface of stainless steel will be destroyed, and its rust resistance will also be reduced. Therefore, when purchasing stainless steel pipes, it is necessary to consider the environment and purpose of use to decide whether to customize deep-drawn stainless steel. In addition, the phenomenon of stainless steel peeling can also cause rust, which requires attention.
The stainless steel wire drawing plate is made of 2B stainless steel plate, which is drawn by ink drawing equipment or wire drawing equipment. At present, the brushed stainless steel plate has become the stainless steel plate with high utilization rate. The surface of stainless steel wire drawing board is smooth as hair, so it is commonly known as stainless steel wire drawing board.
The size and width of the stainless steel wire drawing board are generally 1219mm, and the width is fixed. The lengths are mainly 2438mm, 3048mm, 3500mm, 4000mm, etc.
