Duplex 2205 (UNS S32305/S31803) Stainless Steel Storage Tanks
Duplex 2205 is a two-phase, ferritic, austenitic stainless steel that offers corrosion resistance (PREN range 28-38), durability, and high yield strength. It is the most commonly used of duplex steels. Chemical processors, biofuel facilities, and food manufacturers use Duplex 2205 stainless steel storage tanks for product storage and processing.
Composition and Advantages of Duplex 2205
Duplex 2205 steel is a high-performance, stainless steel alloy with a dual-phase structure. It consists of approximately equal amounts of ferrite and austenite, which gives the material good mechanical strength and corrosion resistance. It offers many advantages for chemical processing and manufacturing stainless steel storage tanks, including:
● Good high-temperature oxidation resistance
● A cost-effective solution compared to austenitic steels such as 317 stainless and AL6XN
● GMAW welding processes use spray arc, pulsed-arc, and short circuit to lower heat input
The high chromium and molybdenum content help Duplex 2205 resist chloride stress corrosion cracking in environments up to 600° F.
Industry Applications for Duplex 2205 Stainless Steel Storage Tanks
Our Duplex 2205 storage tanks are widely used as chemical storage tanks, heater tube shells, and separator tanks in oil and gas, chemical processing, and food manufacturing applications. The tanks are versatile and meet the demanding requirements of these and other industries.
Applications include:
● Biofuels: Duplex 2205 is ideal for reaction tanks, storage tanks, and piping systems used for the storage and processing of biofuels like ethanol and biodiesel.
● Chemical processing: Corrosion resistance makes Duplex 2205 ideal for pressure tanks, transport and storage tanks, and heat exchangers in the chemical industry.
● Dairy: Its high working temperature makes Duplex 2205 a good choice for stainless steel storage tanks used in dairy processing.
● Effluent scrubbing: Our Duplex 2205 storage tanks are ideal for scrubbing systems, including Jet Venturi, multi-stage, and exhaust gas scrubbing systems.
● Health and beauty: Stainless steel storage tanks ensure the cleanliness and safety of shampoo, conditioner, toothpaste, deodorant, body wash, and liquid soaps during manufacturing and transport.
● Food and beverage: Duplex 2205 storage tanks are ideal for food and beverage manufacturers. It resists corrosion from foods with high acid and chloride content while maintaining exacting hygiene standards. Food applications using Duplex 2205 include storage and transport of ketchup, salsa, sauces, soups, eggs, cheese, vinegar-based products, and brine solutions.
The durability, strength, and corrosion resistance of Duplex 2205 storage tanks can benefit many industries.
