A Guide to Stainless Steel Passivation
Stainless steel passivation involves the removing of free ions contaminants which have been left on the stainless steel from fabrication. With these contamination sites likely to cause metal corrosion, it is recommended to use Dorsetware’s stainless steel passivation services to protect your metal products.
What is stainless steel?
Stainless steels are iron alloys made up of at least 10.5% chromium and other alloying elements. Whilst these extra elements are added to ensure the maximum strength of the metal, the main purpose of stainless steel is to be corrosion resistant. This is achieved through stainless steel passivation and is necessary for both domestic and industrial uses of the metal. The need for corrosion resistance can be achieved with Dorsetware’s steel passivation services in Hampshire.
Why is stainless steel passivation needed?
The passivation of stainless steel is vital in resisting premature corrosion and metal deterioration. If the process of steel passivation is not applied effectively, the steel is likely to rust and contain areas which are likely to corrode. Like chrome plating, the passivation of stainless steel prevents this discolouring from rust whilst maintaining the metal’s strength.
How does stainless steel passivation work?
Steel passivation prevents metal corrosion by removing free ions from the metal and forming a passive and transparent oxide film. During the passivation process, this film reacts with the air to form a chromium oxide surface which is resistant to corrosion.
Which stainless steel products require steel passivation?
- Knives, forks and other cookware
- Modern construction and architecture materials
- Surgical and dental instruments
- Car exhaust and engine components
