What is Duplex Steel UNS S31803?
Duplex Steel UNS S31803 is a type of duplex stainless steel combination of austenitic and ferritic steel. It is characterized by its high strength, good corrosion resistance, and excellent resistance to stress corrosion cracking. This type of steel is particularly useful in environments that are highly corrosive, such as offshore oil rigs and marine and chemical processing applications.
Duplex Steel UNS S31803 is commonly used in food processing due to its ability to resist pitting, crevice corrosion, and erosion corrosion. The steel is commonly referred to as 2205 due to its composition of 22% chromium and 5% nickel. This duplex steel offers a good balance of properties, making it an attractive alternative to other stainless steel, especially in harsh corrosive environments.

ASTM A479 Duplex Stainless Steel 1.4462 Bolts has excellent resistance to stress corrosion cracking, and also excellent resistance to localised corrosion including intergranular, pitting and crevice corrosion. ASME SA 479 Duplex Steel UNS S31803 Hex Screws are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.

What is Duplex Steel UNS S32205 Bolts?
Duplex Steel UNS S32205 Bolts are high-strength fasteners made from a duplex stainless steel alloy. This type of steel is a mixture of austenitic and ferritic steel, resulting in a material with high strength and good corrosion resistance. Duplex Steel UNS S32205 Bolts are designed to offer improved resistance to stress corrosion cracking, making them ideal for use in harsh, corrosive environments, such as in marine and offshore oil and gas applications.
These bolts are also commonly used in chemical processing, as well as in the food processing industry. Duplex Steel UNS S32205 Bolts are made to meet international standards, such as ASTM A479, and can be custom-made to meet specific requirements. They are available in various sizes, head styles, and finishes and can be supplied with nuts, washers, and other hardware as required.
In addition to their high strength and corrosion resistance, these bolts offer good fatigue resistance and can be easily fabricated and welded. Duplex Steel UNS S32205 Bolts are an excellent choice for applications that require high strength, good corrosion resistance, and stress corrosion cracking resistance, making them ideal for use in harsh and corrosive environments.
Asiad Steels is one of the known suppliers of ASTM A479 Duplex Steel UNS S31803 & UNS S32205 Bolts, which have good weldability and can be welded by several methods. ASTM A479 Duplex Steel UNS S31803 Hex Bolts finds applications due to excellent corrosion resistance and high strength. ASME SA 479 Duplex Steel UNS S32205 Heavy Hex Bolts are often used in chemical processing, transport, and storage – pressure vessels, tanks, piping, and heat exchangers.
ASTM A479 Duplex Stainless Steel 1.4462 Bolts have excellent resistance to stress corrosion cracking and also excellent resistance to localized corrosion, including intergranular, pitting, and crevice corrosion. ASME SA 479 Duplex Steel UNS S31803 Hex Screws are also magnetic, a property that can be used to differentiate them from common austenitic grades of stainless.
And to never be insular and inward-looking. ASTM A479 Duplex Steel UNS S32205 Round Head Bolts have higher strength which is around twice that of Type 304 austenitic stainless steel. This leads to reduced plate thicknesses being used in fabrications reducing the weight, which is of particular significance in items such as pressure vessels, storage tanks, and structural applications such as bridges. ASME SA 479 Duplex Steel UNS S31803 Square Bolts is hot work in the temperature range of 954-1149 Degrees C (1750-2100 Degrees F). The structure of ASTM A479 Duplex Steel UNS S32205 Allen Cap Screws consists of austenite pools surrounded by a continuous ferrite phase.
