What is 321 Stainless Steel?

Stainless steel 321 is a stabilized austenitic stainless steel alloy that contains titanium as a stabilizing element. It is similar to stainless steel 304 but with the addition of titanium, which provides improved resistance to intergranular corrosion and higher strength at elevated temperatures. Stainless steel 321 is commonly used in applications requiring high-temperature and corrosion resistance, such as in aircraft exhaust systems, chemical processing equipment, and thermal processing units.

Stainless Steel 321 & 321H Round Bar

Stainless Steel 321 is a versatile austenitic stainless steel alloy containing chromium, nickel, and titanium as its primary alloying elements. The addition of titanium provides stabilization against sensitization and intergranular corrosion, making it suitable for high-temperature applications. Stainless Steel 321H is a higher carbon version of 321, offering improved high-temperature strength and resistance to sensitization. Stainless Steel 321 and 321H round bars are solid cylindrical rods made from these respective grades of stainless steel. ASTM A276 is available in various shapes and sizes, including round bars and round rods, to suit different applications and requirements. We are the supplier of Stainless Steel 321 & 321H Round Bar with prices in the industry, and we also provide other products such as 321/321H Bright Bars, 321/321h Black/Forged Bar, 321H Hex Bars and many more.

Our stainless steel 321 round bars are manufactured using high-quality raw materials by industry standards. Grade 321 stainless steel typically contains chromium, nickel, titanium, and other elements to enhance its mechanical properties and corrosion resistance. This composition ensures that our stainless steel 321 round bars meet the highest quality standards and deliver reliable performance in various applications.

We offer a comprehensive range of UNS S32100 round bars at competitive prices to meet our customers' needs. Our bars are available in various shapes, sizes, and lengths to accommodate applications and requirements. Whether you need standard round bars or customized shapes and sizes, we have the right solution for you at a price that fits your budget.

Features of Stainless Steel 321 & 321H Round Bar

  • High-Temperature Resistance: Stainless Steel 321 and 321H Round Bars offer exceptional resistance to high temperatures, making them suitable for use in applications where exposure to heat is common. They retain their mechanical properties and structural integrity even at elevated temperatures, making them ideal for applications such as aircraft exhaust systems and thermal processing units.
  • Corrosion Resistance: ASME SA276 round bars exhibit excellent corrosion resistance, particularly against intergranular corrosion, which makes them suitable for use in corrosive environments. The addition of titanium in Stainless Steel 321 enhances its resistance to intergranular corrosion, ensuring long-term durability and reliability in harsh conditions.
  • Weldability: Stainless Steel 321 and 321H Round Bars are easily weldable using conventional welding methods. This allows for seamless fabrication and installation, making them suitable for a wide range of manufacturing and construction applications where welding is required.
  • Stabilized Structure: The addition of titanium stabilizes the structure of Stainless Steel 321 and 321H, preventing sensitization and ensuring long-term durability. This stabilized structure enhances the mechanical properties of the round bars, making them resistant to deformation and stress cracking under various operating conditions.
  • Versatile Applications: DIN 1.4449 and 321H Round Bars find applications in various industries such as aerospace, chemical processing, automotive, construction, and marine. Their high-temperature resistance, corrosion resistance, weldability, and stabilized structure make them suitable for a wide range of applications where strength, durability, and reliability are required.

321 SS vs 316 SS

Stainless Steel 321 and Stainless Steel 316 are austenitic stainless steel alloys but differ in composition and properties. Stainless Steel 321 contains titanium, stabilizing the alloy against sensitization and intergranular corrosion at elevated temperatures. This makes it suitable for high-temperature applications such as aircraft exhaust systems and thermal processing units. On the other hand, Stainless Steel 316 contains molybdenum, which enhances its corrosion resistance, particularly against chlorides and acids. It is commonly used in marine environments and chemical processing industries. While both alloys offer excellent corrosion resistance and weldability, Stainless Steel 321 is preferred for high-temperature applications, while Stainless Steel 316 is chosen for its superior corrosion resistance in harsh chemical environments.
