This unique composition gives it superior strength, heat resistance, corrosion resistance, and other desirable properties, making it a popular choice for high-performance applications.
This comprehensive guide will explore the properties, uses, and composition of Duplex 2205/31803 Foil. By the end of this article, you will better understand this remarkable material and its potential applications.
What is Duplex 2205/31803 Foil?
Duplex 2205/31803 Foil is a versatile material used in many industries for its superior corrosion resistance, high strength and ductility. It combines the properties of ferritic and austenitic stainless steel. It is composed of about 22% chromium, 3% molybdenum, 5-6% nickel and nitrogen to achieve a higher level of strength compared to other common grades such as 304L/316L. The result is an alloy with twice the yield strength and improved chloride pitting resistance compared to 316L/304L stainless steel alloys. Furthermore, high-temperature creep strength and improved low-temperature toughness make it ideal for marine environments or other corrosive applications. Although more expensive than traditional stainless steel products due to its production process, Duplex 2205/31803 Foil offers numerous advantages over other materials, such as increased corrosion resistance, good weldability, making it easy to fabricate complex shapes without heat treatment, better stress cracking resistance at room temperature and elevated temperatures (up to 500˚F), greater mechanical stability under load cycling conditions and even greater impact toughness at cryogenic temperatures (-320˚F).
