SS Round Bar

Description

Stainless steel bar presents a variety of special advantages for several industries and purposes for the duration of the globe. Stainless steel is one of the most broadly used metals in the modern-day development world.

Property & Specification

1. High strength

2. Corrosion resistance

3. Easier to be plasticity and deformability

   
   

Corrosion

Dust particles attached to the surface can promote the corrosion of stainless steel. When dust particles exist on the surface, gaps are formed where the dust particles are deposited, which easily maintains a water film containing chloride ions, hindering the replenishment of oxygen and causing damage to the passivation film. In addition, this dissolution zone and the passivation zone adjacent to the dust particle deposition will form a blocked cell and intensify the formation and development of pitting pits.

Oxidation treatment

1. Sandblasting (shot) method: Mainly uses the method of spraying micro glass beads to remove the black oxide scale on the surface.

2. Chemical method: Use a pollution-free pickling passivation paste and a normal temperature-non-toxic cleaning solution with inorganic additives for immersion. To achieve the purpose of whitening the original color of stainless steel. After treatment, it looks like a dull color. This method is more suitable for large and complex products.
