![]() ![]() The alloy has excellent resistance to intergranular corrosion in the as-welded condition. The low carbon chemistry of 304L combined with an addition of nitrogen enables 304L to meet the mechanical properties of 304.Īlloy 304/304L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. It is common practice for 304L to be dual certified as 304 and 304L. It is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications. If you need something that is more resistant against extreme temperatures, then 304 grade should be your go-to option, but if you are looking for something more economical, then 201 grade may be a better choice for you as it does not contain as much nickel in its composition which means lower cost over time due to less expensive raw materials used in the production process.Alloy 304/304L (UNS S30400/S30403) is the most widely utilized “18-8” chromium-nickel austenitic stainless steel. Conclusion:īoth 201 and 304 stainless steel have their own set of advantages that make them suitable for various projects depending on your needs. However, 304 stainless steel may require slightly more care than 201 stainless steel due to its higher level of corrosion resistance. Maintenanceīoth types of stainless steel require minimal maintenance. This means that it can better withstand exposure to salt water, acids, and other chemicals. However, 304 stainless steel is more corrosion-resistant than 201 stainless steel. Durabilityīoth 201 and 304 stainless steel are durable materials. ![]() 304 stainless steel is more commonly used in industrial applications, such as chemical storage tanks and food processing equipment. It is also used in some medical applications, such as surgical instruments and hospital beds. UsesĢ01 stainless steel is often used in food service applications, such as restaurant equipment, kitchen utensils, and storage containers. However, it is important to note that both types of stainless steel are more expensive than other types of steel, such as carbon steel. CostĢ01 stainless steel is typically more affordable than 304 stainless steel. The main difference between 201 and 304 stainless steel is the composition. Stainless steel is a metal that is made up of iron, chromium, nickel, and other metals. The two main types of stainless steel are 201 and 304. Difference Between 201 and 304 Stainless Steel Composition Furthermore, due to its higher nickel content (8%) compared to 201-grade stainless steel (4%), it has superior resistance against pitting corrosion caused by chlorides which makes it a very practical choice for food processing industries or marine applications where saltwater exposure might be an issue. This type of stainless steel has excellent heat resistivity up to 1500☏ (816☌), making it ideal for applications that require extensive heating or cooling cycles, such as cookware or industrial kitchen equipment. ![]() It is composed primarily of 18% chromium and 8% nickel, along with small amounts of molybdenum, titanium, nitrogen, silicon, copper, selenium and carbon, which give it its characteristically strong constitution. Composition of 304 Stainless Steelģ04 stainless steel is one of the most popular types on the market due to its high corrosion resistance and strength at a relatively low cost. Additionally, because of its low carbon content (0.15%), it is not susceptible to carbide precipitation during welding or heat treatments like other steels might be. With 17% chromium, 4% nickel, 7% manganese, and 0.15% nitrogen as its primary elements, this type of stainless steel can withstand corrosion better than standard materials. It is engineered with a higher manganese content than other comparable grades in order to enhance its strength and durability. Let’s dive into the details! Composition of 201 Stainless SteelĢ01 stainless steel includes a combination of Cr-Ni-Mn alloys that are specifically designed to be strong and durable while also being cost-effective. This article will provide an overview of what makes 201 and 304 stainless steel unique and how their properties can benefit certain projects. When it comes to selecting the right stainless steel for your project, it is essential to understand the differences between the two most popular types available on the market. ![]()
