Stainless steel is popular in many industries, including construction, automotive, and aerospace. It is known for its strength, durability, and resistance to corrosion. One type of stainless steel commonly used is 347 stainless steel. This material is often used to manufacture round bars, an essential component in many mechanical applications. However, it is important to note some differences between 347 stainless steel round bars and 347 round bars. In this blog post, we will discuss these differences in detail and help you understand which type of round bar best suits your application.
What is 347 Stainless Steel Round Bar?
347 Stainless Steel Round Bar is an austenitic alloy containing chromium, nickel, carbon and titanium. This combination provides excellent corrosion resistance in aggressive environments up to 1500°F (820°C) while offering good mechanical properties and high-temperature oxidation resistance. Its increased chemical stability makes it an ideal choice for applications requiring frequent thermal cycling.
Difference between 347 Stainless Steel Round Bar and 347 Round Bar
Chemical Composition:
One of the primary differences between 347 stainless steel round bars and 347 round bars is their chemical composition. 347 stainless steel contains higher amounts of chromium and nickel than 347 round bars. This makes 347 stainless steel more resistant to corrosion and heat. The higher nickel content also makes it less magnetic than 347 round bars. On the other hand, 347 round bars contain more carbon and less nickel than 347 stainless steel. This makes 347 round bars stronger and more durable than 347 stainless steel.
Manufacturing Process:
Another factor that differentiates 347 stainless steel round bars from 347 round bars is the manufacturing process. 347 stainless steel round bars are manufactured using a cold-drawing process, which involves pulling the steel through a die to create the desired shape and size. This process produces round bars with precise dimensions and smooth surfaces. 347 round bars, on the other hand, are manufactured using a hot-rolling process, which involves heating the steel and then rolling it to form the desired shape and size. This process is known for producing round bars with a rougher surface finish.
Application:
The application is a significant factor when choosing between 347 stainless steel round bars and 347 round bars. 347 stainless steel round bars are commonly used in high-temperature applications such as aerospace and aviation, where resistance to corrosion and heat is critical. It is also used in chemical and pharmaceutical industries where corrosion resistance is necessary. In contrast, 347 round bars are used in construction and heavy-duty machinery applications where the strength and toughness of the material are critical factors.
Cost:
Lastly, the cost is a big factor when choosing between 347 stainless steel round bars and 347 round bars. 347 stainless steel round bars are more expensive than 347 round bars, primarily because of their higher nickel and chromium content. The manufacturing process of 347 stainless steel round bars also increases the cost. If cost is a significant factor in your application, it is recommended to use 347 round bars instead.
Conclusion:
In summary, 347 stainless steel and 347 round bars have notable differences in chemical composition, manufacturing process, application, and cost. Understanding these differences is important in choosing the right material for your application. If corrosion and heat resistance are crucial, 347 stainless steel round bars are recommended, but if strength and cost are the primary considerations, 347 round bars are preferred. This blog post helps you choose the right round bar type for your application.
