Stainless steel can be easily misunderstood based on its name – stainless steel. In reality, during processes such as machining, assembly, welding, and weld seam inspection, stainless steel can accumulate surface contaminants such as oil, rust, metal impurities, welding slag, and splatter. Additionally, in systems where corrosive anions with activating effects are present, these substances can damage the protective oxide film on the surface of stainless steel. This damage diminishes the corrosion resistance of stainless steel, leading to corrosion and triggering various forms of corrosion.
Therefore, it is essential to subject stainless steel to proper anti-corrosion treatment to enhance its corrosion resistance. Empirical evidence demonstrates that only after passivation can keep the surface in a long-term passivation state, thereby improving its corrosion resistance. This precautionary measure prevents various corrosion incidents during usage.
EST Chemical Group has dedicated over a decade to the research and production of metal surface treatments. Choosing EST's stainless steel passivation solution for your company is choosing quality and assurance.
