UNS S32906 Round Bars | ASTM A182 / A182M Super Duplex Stainless Steel Bars
When industries need high strength, excellent corrosion resistance, and long service life, UNS S32906 round bars are one of the most reliable material choices. Known for their super duplex stainless steel structure, these bars perform exceptionally well in marine, oil & gas, chemical, and offshore environments where ordinary stainless steels fail.
We supply UNS S32906 Round Bars manufactured as per ASTM A182/A182M, ASTM A276, and ASME SA276 standards, ensuring consistent quality, dimensional accuracy, and dependable mechanical performance.
What Are UNS S32906 Round Bars?
UNS S32906 stainless steel is a super duplex stainless steel grade with a balanced microstructure of austenite and ferrite. This dual-phase structure gives it:
- Higher strength than standard duplex steel
- Outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking
- Excellent performance in chloride-rich and seawater environments
UNS S32906 round bars are commonly supplied under:
- ASTM A182 UNS S32906 Bars
- ASTM A182 / A182M UNS S32906 Rods
- ASME SA276 ASTM A276 UNS S32906 Stainless Steel Bars
They are also referenced as F65 / UNS S32906 / F65 stainless steel in pressure and structural applications.
Key Features of UNS S32906 Stainless Steel Bars
High Yield & Tensile Strength
Superior Resistance to Chloride Corrosion
Excellent Fatigue & Impact Strength
Better Weldability than many high-alloy steels
Longer service life, lower maintenance costs
Because of these features, ASTM A182 UNS S32906 Round Rods are preferred in safety-critical applications.
Advantages of Choosing ASTM A182 UNS S32906 Bars
- Longer life in aggressive environments
- Reduced risk of corrosion failure
- Lower maintenance and replacement costs
- High load-bearing capacity
- Compliance with international standards
This makes ASME SA276 ASTM A276 UNS S32906 stainless steel bars a cost-effective long-term solution.
UNS S32906 vs UNS S32950 – Understanding the Relationship
Many buyers often see UNS S32906 and UNS S32950 mentioned together. While both belong to the super duplex stainless steel family, they are closely related grades used for similar high-performance applications.
- UNS S32906 is commonly supplied under ASTM A182 and A276
- UNS S32950 is often referenced for flat bars, hex bars, and round bars
You may also encounter related products such as:
- ASTM 276 Super Duplex Steel S32950 Flat Bars
- Super Duplex Steel UNS S32950 Round Bars
- UNS S32950 Hex Bar Supplier in India
All these grades share high PREN values, making them ideal for extreme corrosion environments.
