What is Passivation? How Does Stainless Passivation Work?

Passivation is a post-fabrication best practice for newly-machined stainless steel parts and components.Benefits include Chemical film barrier against rust; Extended life of the product; Removal of contamination from product surface; Reduced need for maintenance.How does passivation work? Stainless steel is an iron-based alloy,typically composed of iron,nickel and chromium.Stainless steelStellar Solutions - Stainless Steel Passivation Citric A worldwide leader in citric acid passivation solutions and other low-hazard products for cleaning and care of stainless steel Passivation of stainless steel has conventionally been accomplished by immersing the steel in a nitric acid bath.This process is both hazardous and environmentally unfriendly.Stellar Solutions has a complete line of stainless steel passivation products for safer and Stainless Steels - Harry BhadeshiaGrain structure of an austenitic stainless steel NF709 (25Cr20Ni).Many of the grains contain annealing twins.NF709 is a creep-resistant austenitic stainless steel used in the construction of highly sophisticated power generation units.Type 302 austenitic stainless steel,cold-rolled and then annealed at 704 china passivation of 416 stainless steel#176;C for one hour.

Stainless steel cannot be passivated unless the steel surface is clean and free from contamination and scale from welding operations.Scale may need to be removed first by 'pickling' or mechanical abrasion and although the surface of freshly pickled stainless steel will normally be immediately passivated once the pickling acid has been washed off,it is important not to regard these two treatments as the
