10/11/2023 0 Comments 18 8 stainless steel strength![]() It is made up of 18% chromium and 8% nickel, called “18-8”. Both materials are excellent choices for fastening products and will serve you well for years.SS 304 is a commonly used stainless steel alloy, recognized as 18-8 Stainless Steel. But if corrosion resistance is your top priority, 18-8 stainless steel is a great option. If you need high strength and durability, A2-70 stainless steel is the way to go. When choosing between these two materials, you should consider the specific requirements of your project. While 18-8 stainless steel is a highly corrosion-resistant material suitable for many applications, A2-70 stainless steel is stronger and more durable, making it ideal for high-performance machinery and aerospace components. In conclusion, the main differences between 18-8 stainless steel and A2-70 are their composition and mechanical properties. Meanwhile, A2-70 stainless steel is often used for: Automotive parts Some common applications of 18-8 stainless steel include: ![]() Common Applicationsġ8-8 stainless steel and A2-70 are widely used in various industries. While it’s not as strong as A2-70, it’s still a highly corrosion-resistant material suitable for many applications, especially those in the food and beverage industry. On the other hand, 18-8 stainless steel has a tensile strength of 620 N/mm² and a hardness of 80 on the Rockwell scale. This makes it ideal for high-strength and durability applications, such as the automotive and aerospace industries. It has a tensile strength of 700 N/mm² and a hardness of 70 on the Rockwell scale. Regarding mechanical properties, A2-70 stainless steel is stronger and more durable than 18-8 stainless steel. It also has a carbon content of 0.12-0.20%, which makes it slightly stronger than 18-8 stainless steel. It contains 17-19% chromium, 8-10% nickel, and 2% manganese. This composition gives it excellent corrosion resistance and makes it suitable for various applications, including kitchen equipment, medical devices, and architecture.Ī2-70 stainless steel, on the other hand, is a more specific grade of stainless steel. Difference Between 18-8 Stainless Steel and A2-70 Compositionġ8-8 stainless steel, or 304 stainless steel, contains 18% chromium and 8% nickel. Additionally, A2-70 provides excellent heat treatability for improved strength and fatigue life. It is typically used in the aerospace and automotive industries due to its superior corrosion and wear resistance. What is A2-70?Ī2-70 is a grade of stainless steel, denoting its mechanical properties: specifically, it has an ultimate tensile strength of 700MPa (101,500 psi). Additionally, it is easy to clean and maintain due to its naturally non-porous surface. It provides excellent corrosion resistance, making it suitable for many different applications in the food processing industry. ![]() What is 18-8 Stainless Steel?ġ8-8 stainless steel is a versatile, strong metal alloy of 18% chromium and 8% nickel. Whether you are a professional engineer or a DIY enthusiast, this guide will help you choose the right material for your next project. This blog post’ll explore the differences between 18-8 stainless steel and A2-70, including their composition, mechanical properties, and common applications. ![]() However, they differ in their composition and strength. Both materials are corrosion-resistant, making them ideal for outdoor and marine environments. Two popular options for fastening products like screws and bolts are 18-8 stainless steel and A2-70.
