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
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.
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.
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.
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.
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.

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.
| Property | UNS N08926 | 316L Stainless Steel | 904L Stainless Steel |
|---|
| Corrosion Resistance | Excellent | Good | Excellent |
| Chloride Stress Corrosion | Superior | Moderate | High |
| Price | Moderate | Low | High |
| Strength | High | Moderate | High |
| Weldability | Excellent | Excellent | Good |
| Temperature Resistance | High | Moderate | High |
