An Overview of 455 Stainless Steel Round Bar

BusinessAn Overview of 455 Stainless Steel Round Bar

Stainless steel is a popular material choice in various industries due to its durability and corrosion-resistant properties. One such type of stainless steel that has made its way into the market is 455 stainless steel. This alloy offers a unique combination of strength, toughness, and corrosion resistance, making it ideal for many applications. In this blog post, we will delve deeper into the features and applications of 455 stainless steel round bars.

What is a 455 Stainless Steel Round Bar?

455 stainless steel is a martensitic steel alloy that contains chromium, molybdenum, and niobium. Its high strength, corrosion resistance, and durability are well-known, making it a popular choice in the aerospace, automotive, and medical industries. Manufacturers produce the round bar form of 455 stainless steel by hot rolling, cold rolling, or drawing, and the finished products typically have a diameter range of 0.250” up to 14”.

Features of 455 Stainless Steel Round Bars

One of the main features of the 455 stainless steel round bar is its high strength, which makes it suitable for high-performance applications. Its toughness and impact resistance also makes it ideal for industries that require materials capable of absorbing shocks and strains. Additionally, the alloy’s heat treatability and formability enhance its versatility, allowing it to be used in various shapes and designs.

Another benefit of the 455 stainless steel round bar is its corrosion resistance, which allows it to withstand harsh environments. The added niobium element in the alloy also contributes to its corrosion resistance, making it a suitable option for marine applications. The alloy is also resistant to sulfuric acid and other acidic environments that corrode many other types of steel.

Applications of 455 Stainless Steel Round Bars

The unique combination of strength and toughness makes the 455 stainless steel round bar ideal for use in the aerospace industry. It is used in aircraft and jet engine components, including bearings, gears, and shafts, due to its high fatigue resistance. The automotive industry also utilizes this alloy in crankshafts and other high-stress engine components. The medical and dental industries commonly use 455 stainless steel round bars, particularly in surgical instruments and implants. Its high strength and corrosion resistance make it a suitable material for these applications.

Machinability and Fabrication

The machinability of the 455 stainless steel round bar is relatively good, considering its high strength. However, it is critical to use the correct cutting tools and machinery to prevent damage to the material. The alloy’s formability makes it relatively easy to work with, allowing it to be moulded into various shapes and designs.


People typically avoid welding 455 stainless steel round bars due to the potential for cracking, especially when welding thick sections. However, if you need to weld, you should use preheating and low heat input to prevent cracking and distortion. It is also vital to use the appropriate filler material to maintain the alloy’s corrosion resistance.


455 stainless steel round bars are an excellent choice for various high-performance applications thanks to their exceptional strength, toughness, and corrosion resistance. The alloy’s versatility and formability suit various industries, including aerospace, automotive, and medical. If you are searching for a durable and corrosion-resistant material that can withstand harsh environments, consider a 455 SS round bar.
