Duplex stainless steels have emerged as a popular choice for industrial applications due to their exceptional strength and corrosion resistance. Duplex UNS S32304 is a type of duplex stainless steel that offers a unique combination of mechanical, physical and chemical properties. This makes it ideal for various industries, from manufacturing to chemical processing. This article will explore seven common applications of Duplex UNS S32304.
What is Duplex UNS S32304?
Duplex UNS S32304 is ferrite-austenite stainless steel comprised of 18% chromium (Cr), 3% molybdenum (Mo), and 2.5 nickel (Ni). It offers excellent corrosion resistance in both oxidizing and reducing environments. With a range of -100°F to 1000°F, it also has great stress corrosion cracking resistance. This alloy requires no stabilization post-welding for long-term durability, making it widely used in marine industries where saltwater exposure is constant. It’s also an ideal choice for applications involving high temperature, low pH levels or extreme chloride contents, such as oilfield equipment, chemical processing vessels and piping systems. Its durable performance capabilities make this alloy highly popular among engineers looking for reliable solutions with superior corrosion protection and long-term stability at higher temperatures.
