![]() 18-8 stainless steel yield strength is also impressive. This type of stainless steel is also not only extremely budget-friendly, but it also requires little to no maintenance. On the up side, 18-8 grade stainless steel properties include the fact that it can be bent and molded without it having an effect on its overall strength and durability. Therefore, it is not the ideal stainless steel to use for marine applications. However, it is known to show signs of corrosion when exposed to chlorides, such as salt. Pros and Cons of 18-8 Grade Stainless SteelĪs already mentioned, 18-8 grade stainless steel is celebrated for its superior corrosion resistance. It can be hardened only by cold working, and it isn’t magnetic. 18-8 type stainless steel has better resistance to corrosion than the 400 series. ![]() That means that an 18-8 grade fastener has 18% chromium and 8% nickel content. This refers to the 300 series of stainless steel with a chromium and nickel content in percentages. Here’s what you need to know about each of these three different grades: 18-8 Grade Stainless Steel Professionals must know what the difference is between 18-8 vs. Whether you are buying nuts, bolts, nails and screws, rivets and pins or anchoring systems, you must take the environment into consideration. The type and grade of stainless steel fasteners that you invest in will determine just how corrosion resistant they are and, of course, how durable and long-lasting you can expect them to be. While 303 stainless steel still has strong corrosion resistance, for an added boost, 304 stainless steel is recommended.Many people mistakenly believe that all stainless steel is the same. These components require more accurate machining specifications due to the required tolerances. The small addition of sulfur slightly reduces corrosion resistance but increases machineability which is why you will find its use in fasteners, bushings, bearings and other smaller components. 304 stainless steel is considered the most versatile and common austenitic stainless steel and is more cost effective compared to 316 stainless steel.ģ03 is a free-machining grade of 304 stainless steel that contains a minimum of 17% chromium, 8% nickel and 0.15% sulfur/selenium. This durability provides ease for fabrication and prevention of product contamination. This stainless steel type is oxidation and corrosion resistant. We will review the main grades of stainless steel in the 300 subgroups as these are the most widely used grades.ģ04 stainless is a low carbon steel that contains a minimum of 18% chromium and 8% nickel which gives the metal its alternate name: 18/8 stainless steel. The subgroups of austenitic stainless steel are 300 and 200. Austenitic stainless steel is non-magnetic and its structure allows for the material to be hardened. ![]() The most widely used and popular is austenitic. The main types of stainless steel alloys are austenitic, ferritic, martensitic, duplex and precipitation hardening stainless steels. In this post, we dissect stainless steel and the different grades of each. Stainless steel is a popular and affordable choice in the packaging industry, especially for food grade applications. There are a variety of materials to choose from with many different specifications tied to them. Choosing the correct material is critical to any application especially those designed for wash-down, corrosion resistance, heat resistance or strength. ![]()
