What is 8 18 and Why You Need to Know It!

8 18 is a term that is commonly used in the world of industry and manufacturing. It is a shorthand way of referring to a specific type of material, namely 18-8 stainless steel. Here’s everything you need to know about 8 18 and why it is important.

What is 18-8 Stainless Steel?

18-8 stainless steel is a type of stainless steel that is composed of 18% chromium and 8% nickel. It is also referred to as 304 stainless steel in the industry. This type of stainless steel is known for its resistance to corrosion, making it a popular choice for a wide range of applications. 18-8 stainless steel is also known for its durability, strength, and versatility.

When it comes to the composition of 18-8 stainless steel, the 18% chromium gives the material its corrosion-resistant properties. The 8% nickel, on the other hand, makes the steel tough and durable. With this combination of elements, 18-8 stainless steel is ideal for use in harsh environments where corrosion could be a problem, such as in marine applications, chemical processing plants, and food processing facilities.

Why is 8 18 Important?

Knowing what 8 18 means is important because it helps you identify the type of stainless steel being used in various applications. If you are working in an industry that requires the use of stainless steel, it is crucial to know which type of stainless steel is being used to ensure that the material is appropriate for the task at hand.

For example, if you are working in a marine-based industry, you would want to use 18-8 stainless steel as it is highly resistant to corrosion in saltwater environments. On the other hand, if you were working in an application that required a high level of strength, you may want to consider a different type of stainless steel that is better suited to the task.

The Properties of 18-8 Stainless Steel

As mentioned earlier, 18-8 stainless steel is known for its resistance to corrosion and durability. In addition to these properties, 18-8 stainless steel also has the following characteristics:

  • High tensile strength
  • Good formability
  • Excellent weldability
  • Excellent resistance to oxidation
  • Low thermal conductivity
  • Non-magnetic

These properties make 18-8 stainless steel ideal for use in a range of industries, including automotive, aerospace, medical equipment, and more.

Uses of 18-8 Stainless Steel

Given its resistance to corrosion, high strength, and durability, 18-8 stainless steel is used in a wide range of applications. Some common uses of 18-8 stainless steel include:

  • Automotive parts
  • Medical equipment
  • Food processing equipment
  • Chemical processing equipment
  • Aerospace components
  • Marine hardware
  • Construction materials

When it comes to choosing the right type of stainless steel for a specific application, it is important to consider the environment in which the material will be used, as well as the specific properties required for the task at hand.

How to Identify 18-8 Stainless Steel

Identifying 18-8 stainless steel is relatively easy. The material is typically marked with a label that reads “18-8” or “304” to indicate its specific composition. In addition, the material will have a distinctive shiny silver appearance that is characteristic of stainless steel.

Conclusion

8 18, or 18-8 stainless steel, is a type of stainless steel that is widely used in a range of industries due to its durability, strength, and resistance to corrosion. Understanding the properties of 18-8 stainless steel is important for anyone who works with stainless steel in any capacity. By knowing what 8 18 means, you can ensure that you are using the right type of stainless steel for the task at hand.
