Finding the right Flange S32750 Supplier ensures quality and reliability in critical applications.
In this guide, we will explore the unique features, advantages, and industrial uses of Flange S32750, helping you make an informed decision when sourcing this essential component.
1. What is Flange S32750?
Flange S32750 is made from Super Duplex Stainless Steel 2507, which consists of high levels of chromium, molybdenum, and nitrogen. This composition enhances its resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for harsh environments.
Key Chemical Composition:
- Chromium (Cr): 24-26%
- Nickel (Ni): 6-8%
- Molybdenum (Mo): 3-5%
- Nitrogen (N): 0.24-0.32%
- Iron (Fe): Balance
This unique blend of elements provides outstanding corrosion resistance, high tensile strength, and excellent weldability.
2. Strength and Mechanical Properties
Flange S32750 is well-known for its superior mechanical properties compared to standard austenitic stainless steels. Its strength and toughness make it suitable for high-pressure and high-temperature applications.
Mechanical Properties:
- Yield Strength: 550 MPa (79.8 ksi)
- Tensile Strength: 795 MPa (115 ksi)
- Elongation: 15%
- Hardness: ≤310 HB
These properties allow Flange S32750 to withstand extreme pressure and mechanical stress, ensuring longevity in industrial environments.
3. Corrosion Resistance of Flange S32750
One of the primary advantages of Flange S32750 is its excellent corrosion resistance. It outperforms standard stainless steel grades, particularly in aggressive environments.
Corrosion Resistance Features:
- Pitting and Crevice Corrosion Resistance: The high molybdenum and chromium content prevents localized corrosion in chloride-rich environments.
- Stress Corrosion Cracking Resistance: Its duplex structure reduces susceptibility to chloride-induced stress corrosion cracking, making it ideal for offshore and chemical industries.
- Oxidation Resistance: Performs well at elevated temperatures, resisting oxidation and scaling.
These corrosion-resistant properties make Flange S32750 a preferred choice in highly corrosive applications.
