What is quality 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.
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:

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.
