UNS N08926 Stainless Steel Round Bar / SS Bars Alloy 926 ASTM A276 Diameter 5 - 350mm

UNS N08926 stainless steel round bars (also known as Alloy 926) are high-performance materials commonly used in applications requiring superior corrosion resistance and strength. They are manufactured according to ASTM A276 standards and are available in diameters ranging from 5 mm to 350 mm. This alloy is ideal for industries such as chemical processing, oil and gas, marine, and heat exchangers due to its excellent resistance to a variety of aggressive environments.

What is UNS N08926 Stainless Steel?

UNS N08926, or Alloy 926, is a high alloy stainless steel that contains a combination of chromium, nickel, and molybdenum. This composition gives it exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, making it highly effective in environments containing chlorides, acids, and other aggressive chemicals. UNS N08926 is particularly suited for applications in highly corrosive environments where standard stainless steels like 304 or 316 may not perform adequately.

Key Features of UNS N08926 Stainless Steel Round Bar

1. Excellent Corrosion Resistance:
   UNS N08926 offers outstanding resistance to chloride-induced stress corrosion cracking and pitting corrosion. It is also resistant to general corrosion and oxidation, making it a prime choice for marine, chemical, and petrochemical industries.

2. High Strength:
   Alloy 926 exhibits superior tensile strength, which enhances its performance in load-bearing applications. This makes it an excellent material for both structural and pressure vessel components.

3. Outstanding Weldability:
   The weldability of UNS N08926 is one of its strongest advantages. It can be welded using standard procedures, and no special pre- or post-welding heat treatments are typically required.

4. Resistant to High Temperatures:
   This alloy can withstand temperatures up to approximately 1000°F (537°C) in continuous service and is effective in a range of environments where elevated temperatures are common.

5. Versatile in Many Industries:
   Due to its high resistance to corrosion, strength, and excellent mechanical properties, Alloy 926 is used in a wide range of industrial applications, such as in chemical reactors, heat exchangers, and desalination plants.

Technical Specifications

The following table provides the detailed technical specifications of UNS N08926 stainless steel round bars:

Mechanical Properties

UNS N08926 offers a variety of mechanical properties that make it ideal for high-strength applications in corrosive environments. The alloy's ability to maintain structural integrity under stress and in high-temperature conditions is one of its key advantages.

Tensile Strength

The tensile strength of UNS N08926 ranges from 80,000 to 100,000 psi (550-690 MPa), which makes it a great choice for applications where high strength and resistance to fatigue and cracking are crucial.

Yield Strength

The minimum yield strength of Alloy 926 is around 35,000 psi (240 MPa). This allows it to withstand considerable stress before deforming.

Elongation

The elongation of UNS N08926 is at least 40%, which gives the alloy good ductility and makes it easier to form and fabricate.

Hardness

The alloy typically has a hardness of 220-250 Brinell hardness (HB), which makes it wear-resistant and durable in demanding applications.

Applications of UNS N08926 Stainless Steel Round Bars

The versatility and robustness of UNS N08926 round bars make them suitable for use in a variety of industries and applications:

1. Chemical and Petrochemical Industry

UNS N08926 is widely used in chemical reactors, heat exchangers, and piping systems for handling highly corrosive substances, including acids, chlorides, and gases. Its resistance to stress corrosion cracking and pitting makes it particularly well-suited for chemical processes that involve high-temperature and high-pressure conditions.

2. Marine Applications

Alloy 926 is an ideal material for marine environments, where exposure to saltwater can lead to corrosion issues. Its exceptional resistance to chloride-induced corrosion makes it a popular choice for seawater desalination plants, shipbuilding, and offshore oil and gas rigs.

3. Heat Exchangers

Heat exchangers, especially those used in the petrochemical, power generation, and HVAC industries, benefit from the high resistance of UNS N08926 to scaling, corrosion, and erosion. The alloy’s ability to withstand both high pressure and high temperatures makes it perfect for these applications.

4. Power Generation

Alloy 926 is used in various components of power plants, including turbine blades, heat exchangers, and condenser tubes. Its resistance to corrosion and high strength are crucial for ensuring long-term durability and performance in these high-stress, high-temperature environments.

5. Nuclear Industry

The nuclear power industry uses UNS N08926 in components that need to endure extreme conditions while maintaining integrity, such as steam generators, reactor cores, and coolant systems.

6. Food Processing and Pharmaceutical Industries

This stainless steel alloy is also used in food processing equipment and pharmaceutical machinery due to its excellent corrosion resistance and ease of cleaning.

Comparison with Other Stainless Steels

UNS N08926 is often compared to other stainless steels like 316L, 904L, and 310 for its corrosion resistance and performance in harsh environments. While 316L is generally resistant to most acids and chemicals, it does not offer the same level of resistance to chloride-induced stress corrosion cracking as UNS N08926. Additionally, 904L offers similar corrosion resistance but is generally more expensive than Alloy 926.

Conclusion

UNS N08926 stainless steel round bars (Alloy 926) are an excellent choice for applications requiring outstanding corrosion resistance, high strength, and durability. Their resistance to pitting, crevice corrosion, and stress corrosion cracking makes them ideal for industries dealing with aggressive chemicals, marine environments, and high-temperature conditions. With their impressive mechanical properties and versatility across multiple industries, UNS N08926 round bars offer a reliable solution for challenging and demanding environments.
