The fact that stainless steel is so resistant to corrosion and can stand up to a lot of wear and tear makes it the ideal substance for long-term use.
Stainless steel has different grades which are used to make fasteners are as follows:
18-8 stainless steel: This grade of stainless steel fastener is the most common, and it’s great for freshwater marine applications. It won’t corrode or rust, but it will lose its shine if you leave it out in the rain too long.
It’s made up of 18% chrome, 8% nickel, and .08% maximum carbon. It’s also known as AISI 316 stainless steel, which means it meets a certain quality standard set by the American Iron and Steel Institute.
Stainless Steel Fasteners Applications
Stainless steel fasteners are used in all kinds of industries—from construction and engineering to architecture and they are a great option for any application that requires strength, durability, and longevity.
304 Stainless Steel – 304 Stainless Steel is an alloy steel that consists of 17% chrome, 8% nickel, and 0.08% maximum carbon. It has a balance between high strength and ductility, making it an excellent choice for applications where high strength is needed but ductility is important.
304 Stainless Steel is popular in food service and colouring applications because it is resistant to organic acids. In addition, it’s a material of choice for the manufacturing of fasteners like machine screws and cap screws because it can withstand high temperatures without becoming brittle or cracking.
305 stainless steel: Cold heading properties of 18-8 were the main reason for creating this grade. However, even though type 304 is called work-hardened steel, the grade is not for use in manufacturing work-hardened items. Comparable to Type 304 in terms of corrosion resistance and material properties. For attaching wood or composite boards to deck beams, deck screws made of stainless steel 305 are commonly used.
316 stainless steel: This stainless steel grade is utilized and advised for use in tough or extreme situations. Because it is more corrosion resistant than 18-8 stainless, we advocate using Stainless Steel 316 Fasteners in saltwater settings. It is essential to remember that even salt in the air near a body of seawater can cause harm to dry applications, thus 316 is the best material. Boats, docks, and piers are common uses for stainless steel 316 fasteners.
410 stainless steel: 410 stainless steel is a ferritic, straight chromium alloy that is melted as an AOD melt type. This alloy is used in many different applications from pump shafts to fasteners and even aircraft landing gear. It is known for its strength and good corrosion resistance. 410 Stainless Steel can be hardened by air cooling from the heat-treating process. It is used for making roofing screws, siding screws, self-tapping
