In such work applications, the 316 stainless steels will last longer than 304 stainless steels-this means many extra years of useful life. ![]() If your application involves corrosive substances such as chloride, marine, or medical environments then paying a premium for grade 316 stainless steel is worth it. When to use stainless steel 316 over 304? Aesthetic Appearance: This metal is attractive on its own, whether it’s polished to a high shine or has a satin finish.Durability: Stainless steel is virtually indestructible and has a significant strength-to-weight advantage, making them desirable when looking for vandal-resistant options. ![]() Hygiene: This a high-stakes benefit, especially when it comes to restroom / bathrooms fixtures, food preparation areas, food display cabinets, and associated accessories like water coolers/bottle fillers.This includes sterilization processes that involve heating with disinfectants and other cleaning chemicals. Corrosion Resistance: Especially when you are using products that come into regular contact with water both in liquid and vapour form, inclusive of fresh and sea water, corrosive chemicals, food preparation or medical applications.Stainless steel has numerous advantages over other metals including corrosion resistance, durability, aesthetics and so much more. What Are the Benefits of Stainless Steel? The structural rivets range with more than one grade of stainless includes Magna-Lok, Allok and Orlock rivets. Most of the Huck Aerobolt range of fasteners indicate the grade of stainless including rivets, nutserts, rivnuts and so much more. Its ability to resist acids, chlorides, including salt, makes grade 316 ideal for numerous chemical, food, and marine applications. The increased nickel content and the inclusion of molybdenum allows for grade 316 stainless steel to have better chemical resistance than the 304 stainless steels. The most basic difference between grade 304 and grade 316 stainless steels is that 316 tends to have more nickel and a bit of molybdenum in the mix, which makes it considerably more expensive. Stainless steel also contains other elements such as nitrogen, nickel, and molybdenum. The key component is chromium, a trace mineral that ensures the metal does not rust. What is stainless steel? Stainless steel is an alloy, which means it is made up of a combination of elements. In this beginner’s guide to Rivets - Stainless 304 Vs 316, we will investigate the differences between the grades as well as suitable applications. Before we begin, let’s start with the basics. To the naked eye, you are not able to see the different grades of stainless, however the difference will make itself more apparent over time. In this blog we will investigate the differences between 304 & 316 grade stainless steel in relation to structural and standard rivets. Size not listed? Please make an enquiry – we may be able to provide it.Understanding stainless steel and the different grades. = Zinc Plated Steel // = A2 Stainless Steel // = A4 Stainless Steel Non-standard sizes and materials are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Rivet Nut Countersunk Knurled Closed End are available in diameters from M3 to M12 to suit various grip ranges.Īvailable at Fastenright in Zinc Plated Steel, A2 Stainless Steel and A4 Stainless Steel as standard. Installing these rivet nuts is simple, using a special tool with a threaded stud, or nose, that engages with the internal threads of the rivet nut and pulls upwards, deforming the unthreaded section of the rivet nut to expand under the reverse side of the material – providing a high strength permanent thread in a thin sheet material. ![]() The closed-end blocks any form of contamination getting to the component, and also prevents the use of screws that are too long for the application. The presence of the knurled body on the rivet nut provides greater resistance to movement within the application than knurling under the head, especially when installed in softer materials. Both types offer a flush, finished appearance to the application. Where the thickness of the application is smaller, the reduced countersunk type is often chosen instead. The full countersunk head is chosen over a reduced countersunk head type due to its stronger nature, however it is also deeper, meaning that it can only be used in material thicknesses greater than 1.5mm. Rivet Nut Countersunk Knurled Closed End, also referred to as Rivnuts, Blind Nuts and Nutserts®, are an internally threaded insert often used when the thickness of the application at hand is too small to tap a standard thread.īy using rivet nuts, a strong thread is created in thin sheets of material, for high strength fastening from bolts and other threaded articles.
