The ideal fastener is the stainless steel fastener because it is durable and performs well under most circumstances apart from being anti-rust and corrosion. The combination that they have of iron and alloy elements like chromium, nickel, molybdenum, and other molecules gives it a superior and long-lasting strength. It also improves iron to be resistant to rust and corrosion. Even with all these advantages of stainless steel screws in mind, one should be careful while choosing the kind of screw according to their requirement. Here are a few things that one must know before they use the stainless steel screws:
1. Choosing The Right Grade
There are a variety of different grades which have their own pros and cons. So, one should keep all of the kinds of grades in mind while picking one that they need. The most used grades are 304 and 316. If the environment that is the stainless steel screws are going to be used is corrosive, i.e. has chemicals or saltwater then 316 grade should be used because it prevents corrosion better because of which the life of the material is significantly increased.
2. Lubricate Threads
All the experts who work with stainless steel fasteners recommend that a lubricant should be used while installing the screws to avoid wear and increase the life of the screws. They should be lubricated while being installed so that they do not get jammed or damaged.
3. The Right Surface Finish Is Important
The better the finish is, the longer the product will last. This is because a smoother finish leads to more corrosion resistance. The reason behind this is that between the irregularities on the surface, dust particles can get stuck which causes friction and make functioning hard.
4. Consider Electro-polishing
Electro-polishing is a process of finishing that is done to remove the thin layer of material that is coated on top of an alloy typically. The process is done to make the surface of the metal shiny and smooth. The process also improves the performance of the metal against corrosion and rust by making the protective chromium oxide layer even thicker.
5. Have a cleaning schedule and follow-through
Stainless steel products, although very durable, do require clean ups and maintenance. A cleaning schedule is also important because dust particles and other contaminants can actually break the protective layer and make the material more prone to rust. That is why it is important to have a schedule for cleaning the products and to follow through with it every now and then to maintain the performance as well as the appearance.
6. Exposure to rainwater
Stainless steel is rust-resistant which means that it doesn’t corrode when it comes in contact with moisture or with air. Stainless steel has a layer of chromium which protects it from moisture and gives it anti-rust properties. Rainwater, however, can increase the chances of corrosion so it is better to consider other ways to improve its anti-corrosive properties. This happens because the contaminants coming in contact with the protective layer can damage it making it easy for moisture to penetrate and cause harm.
