Super Duplex Stainless Steel S32750, also known as “2507” or “F53”, is a high-grade stainless steel alloy composed of 25% chromium, 7% nickel and 3.7% molybdenum. It has excellent corrosion resistance due to its high chromium and molybdenum ratios combined with its low carbon content. This allows it to have superior weldability and provides a combination of strength/toughness which can be matched by only a few other alloys making it ideal for use in environments such as highly corrosive petrochemical process environments and handling chemical solutions. Additionally, this grade has good formability characteristics making it suitable for any application requiring frequent bending or complex shaping operations. Overall, S32750 is undoubtedly one of the most versatile super duplex stainless steels on the market today, making it an invaluable material for use in many industrial applications!
In terms of high-performance stainless steel alloys, Super Duplex 2507 (UNS S32750) emerges as the best material, renowned for its excellent strength, resistance to corrosion, and versatility, especially in environments resistant to uniform corrosion. It is widely used in harsh conditions, such as the chemical industry, marine engineering, and oil and gas exploration. This duplex stainless steel has a unique combination of mechanical properties and resistance against extreme conditions. This blog provides a comprehensive understanding of Super Duplex 2507, starting from its chemical composition, key properties, and applications to the benefits it comes with.
The Super Duplex Steel S32750 forged pipe fittings are characterized by excellent resistance to pitting corrosion. They have high oxidation resistance as well as heat conductivity. They are appropriate for operation up to 300 degrees. They are also corrosion-resistant in non-oxidizing acids and sturdy alkalis. The alloy has a slight reduction in impact energy as the temperature decreases. No ductile-brittle transition also characterizes the alloy. They have increased tensile strength and are a cost-effective solution.
Super Duplex Steel UNS S32750 Forged Pipe Fittings are mainly used in offshore platforms. They are suitable for applications with high temperatures and harsh environments. Withstand corrosion in a wide range of chemicals. Stainless Steel UNS S32750 Forged Pipe Fittings have a low carbon content that prevents carbide formation during heat treatment. They have higher strength properties than other austenitic grades. They can be welded or cold formed. They are available in different sizes and shapes. Moreover, they are characterized by excellent resistance to pitting and localized corrosion. These fittings are also suitable for applications that involve chlorine solutions.
Super Duplex Steel UNS S32750 Forged Pipe Fittings have highly demanded their excellent features. The alloy contains a high amount of chromium and molybdenum. This helps them to be stronger and withstand extreme temperatures. In addition, it has been shown to offer better corrosion resistance than conventional stainless steel. The alloy is commonly used as a replacement for 300 series stainless steel and high nickel super austenitic steels.
The super duplex steel S32750 is an alloy known for its great strength and excellent corrosion resistance, making it suitable for use in tough environments. This metal’s chemical composition is carefully balanced to give a combination of good mechanical properties and outstanding resistance to various types of contamination, such as crevice and pitting corrosion. Here is the complete list of its components:
Chromium (Cr): 24.0% – 26.0% – Boosts its resistance to corrosive substances, particularly oxidizing agents.
Nickel (Ni): 6.0% – 8.0% – Improves toughness and corrosion resistance by stabilizing the austenite phase.
Molybdenum (Mo): 3.0% –5.0% – Possesses excellent resistance to localized corrosion like pitting or crevice corrosion in chloride-containing environments.
Nitrogen (N): 0.24%—0.32%—It reinforces the material while developing immunity against localized cracking.
Carbon (C): Max 0.03 % – Maintained at low levels to prevent carbide precipitation and retain good corrosion resistance.
Manganese (Mn): max1.2 %– For structural stability thereby improving weldability
Silicon (Si): Max of about .8%. It increases oxidation resistance at high temperatures.
Phosphorous(P): Max of .035%. Controlled so as not to cause brittleness
Sulfur(S): Max of .02 %. Reduced to improve toughness and purity, thus providing superior tolerance to chemical attack for S32750.
