Understanding Duplex Steel F53
Duplex Steel F53 Round Bars Supplier in India, also known as UNS S32750, is a super duplex stainless steel with high levels of chromium, molybdenum, and nitrogen. This composition enhances its resistance to pitting, crevice corrosion, and stress corrosion cracking, making it an ideal choice for harsh environments. The unique duplex microstructure, a mix of austenite and ferrite phases, provides increased strength and better resistance to corrosion compared to conventional stainless ...
... steel. Here’s an in-depth look into what makes Duplex Steel F53 Round Bars Manufacturer a top choice for many applications.

Chemical Composition of Duplex Steel F53
Chromium (Cr): 24.0 – 26.0%
Nickel (Ni): 6.0 – 8.0%
Molybdenum (Mo): 3.0 – 5.0%
Nitrogen (N): 0.24 – 0.32%
Iron (Fe): Balance
Other Elements: Manganese, Silicon, Phosphorus, Sulfur
This balanced composition ensures the material exhibits excellent mechanical and corrosion-resistant properties.
Key Properties of Duplex Steel F53 Round Bars
High Strength and Toughness: The duplex structure gives the material superior mechanical strength, making it more durable than standard stainless steel.
Excellent Corrosion Resistance: Its high chromium and molybdenum content ensures outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
Good Weldability:Duplex Steel F53 Round Bars offers excellent weldability and can be welded using standard methods without the need for preheating.
High Thermal Conductivity: The material has better thermal conductivity than austenitic stainless steel, which is beneficial in heat exchanger applications.
Lower Thermal Expansion: Compared to austenitic steels, it has a lower thermal expansion coefficient, reducing deformation in high-temperature applications.
Cost-Effective Alternative: Due to its high strength, lower material thickness can be used, reducing overall material costs without compromising performance.
