Stainless steel is used for countless purposes in manufacturing, such as pipes, cookware, cutlery, kitchen sinks, building structures, garden equipment, appliances, and more. As it is an alloy, it depends on protection to remain strong, sturdy, and reliable; otherwise, it could succumb to rust and corrosion that will make it destructive.
Fortunately, various steps are available to retain its quality and dependability throughout the years. Learn how manufacturers can protect stainless steel from rust and corrosion.
Keep Stainless Steel Dry
Every manufacturer or construction site must attempt to keep stainless steel material as dry as possible. It might sound easier said than done with moisture in the air, but doing so will prevent corrosion or rust from forming.
Embrace Passivation
A thin layer of chromium can protect stainless steel by improving its resistance to water, damp air, or other forms of moisture. The passivation process stops iron from becoming chemically reactive, avoiding corrosion. A protective layer is developed by combining chromium with oxygen, creating chromium oxide (Cr203), and passivation ensures the material is effectively protected in an instant. However, all stainless-steel equipment must be thoroughly cleaned to prevent compromising passivation and to reduce its risk of rust and corrosion.
Chromium is a must-add addition to stainless steel that will experience regular exposure to water and damp air. For instance, you should learn more about the benefits of adding chromium to iron pipes, as it will protect the material from rust and corrosion to create a more hygienic environment.
Apply a Steel Lubricant
In addition to adding chromium to iron, it may help to apply a steel lubricant to parts that will often move, such as door hinges, bearings, and joints. A water-based lubricant will support the good movement of a joint or hinge while repelling moisture throughout the years. It is an extra layer of protection that will provide manufacturers with peace of mind that their stainless-steel equipment will function well and has a lower susceptibility to corrosion.
Avoid Scratches and Cracks of Any Size
It is imperative to avoid using stainless steel with any scratches or large to tiny cracks, as it will increase its exposure to moisture and may even hold onto water. Cracks and scratches could boost the likelihood of water and moisture coming into contact with iron, causing rust to form.
For this reason, it might be beneficial to use cold-rolled steel, as it will provide a more durable metallic surface that will not trap moisture. Also, only use non-abrasive tools when caring for stainless steel, such as soft cloths and stainless-steel pads, and you should always clean in the direction of its polishing marks.
It doesn’t matter if you are making hygienic pipes and valves or cookware and cutlery; you must protect stainless steel from rust and corrosion to improve its hygiene, structural integrity, and longevity. Passivation is a must-do, but you also must avoid using materials with scratches and cracks and limit their exposure to moisture when possible.
