1. What is the Passivation of Stainless Steel?

2. INTRODUCTION

3. Passivation is a prominent metal finishing process, which makes the products, like stainless steel, corrosion-resistant. The passivation process involves the submersion of stainless steel in nitric acid or citric acid for some time to remove free iron from their surface, which causes corrosion when exposed to air. This chemical treatment eliminates free iron and leads to the formation of a protective oxide layer that is less likely to react with air. The best mechanical constructions in Saudi Arabia offer passivation and preservation of equipment.

5. Why passivate stainless steel? Passivating stainless steel is rather crucial for many reasons, such as: To form a chemical barrier against rust To extend the life of the stainless steel To remove contaminants from the product surface To reduce the need for regular maintenance.

6. Passivation is basically a post-fabrication process done after grinding, welding, cutting and other machining operations on stainless steel, sort of like an end procedure, a final touch. Because upon manufacturing stainless steel, it gets exposed to many conditions such as the following that will increase the chances of corrosion:

7. Foreign particles present in the manufacturing environment like shop dirt, grinding swarf etc. Variant sulfides mixed to the material for improved machinability. Iron particles stuck on the stainless steel from adjacent machinery and cutting tools.

8. CONCLUSION

9. All these contaminants from the manufacturing unit need to be removed from the surface to restore the corrosion resistance of stainless steel. The passivation process rectifies corrosion issues, thus, is an important service offered by the best mechanical construction companies in Saudi Arabia.
