Stainless steel is an alloy of iron, chromium, and other metals, such as nickel and molybdenum. It is an extremely strong and durable material that is widely used in a variety of industries, from automotive and construction to medical and food processing. It is highly resistant to corrosion and can withstand high temperatures, making it an ideal choice for many applications.

Duplex stainless steel plate offers high strength and excellent corrosion resistance, while Super Duplex plate offers higher strength and better corrosion resistance. Duplex plate is a combination of austenitic and ferritic stainless steel and is more corrosion resistant than the traditional 300 series stainless steel. Super Duplex plate is composed of a higher percentage of chromium and molybdenum, which gives it enhanced strength and corrosion resistance. The higher chromium and molybdenum content also makes Super Duplex more expensive than Duplex.

What are grades of Duplex plate ?

Duplex plate grades are typically divided into two categories; ferritic and austenitic. Ferritic grades are typically used in applications where strength, corrosion resistance, and cost are all important factors. Common ferritic grades include UNS S31803 (also known as 2205), UNS S32304, and UNS S32750. Austenitic grades are often used in applications where higher corrosion resistance is paramount and are generally more expensive than ferritic grades. Common austenitic grades include UNS S32760, UNS S31254 (also known as 6Mo), and UNS S32900.

What are grades of super duplex plate ?

Super duplex plate is typically available as a cold-rolled product in the annealed condition with a maximum Brinell hardness of 270. These plates are typically dual certified as per EN 10204 3.1 and ASTM A240. Common grades of super duplex plate include UNS S32750 and UNS S32760. Both these grades offer excellent corrosion resistance, good weldability and a high strength-to-weight ratio, making them ideal for applications in industries such as marine, oil and gas, and chemical processing.

Super duplex stainless steel plates are highly alloyed stainless steel plates that offer excellent corrosion resistance, superior mechanical properties and strength, and a wide range of applications. In Qatar, the grades of super duplex plates commonly used include UNS S32750 (Alloy 2507), UNS S32760 (Alloy Zeron 100), and UNS S32950 (Alloy 32750).

Alloy 2507 (UNS S32750) is a 25% chromium, 7% nickel, 4% molybdenum super duplex stainless steel plate with high strength and excellent corrosion resistance. It is the most widely used grade of super duplex plate in Qatar due to its excellent mechanical properties, good weldability, and high corrosion resistance. It is often used in the oil and gas industry for its superior corrosion resistance in highly corrosive environments.

Alloy Zeron 100 (UNS S32760) is a 25% chromium, 7% nickel, 4% molybdenum super duplex stainless steel plate with excellent corrosion resistance and high strength. It is typically used in the oil and gas industry as well as in chemical processing due to its superior corrosion resistance in highly corrosive environments.

What is the price and properties of duplex plate ?

Duplex Plates are a popular choice among industries in Qatar due to their high strength and corrosion resistance. The cost of duplex plates depends on the grade, size, and other properties. Generally, duplex plates range in price from $2,200 to $5,000 per ton. The standard specifications for duplex plates include ASTM A240, A240M and EN 10088-2. These plates are available in various sizes and thicknesses, and offer excellent mechanical properties, such as high strength and good weldability. Additionally, they exhibit excellent corrosion resistance and can be used in high pressure and temperature applications.

How can I import Super Duplex plate into Qatar without having to pay customs?

Importing Super Duplex Plate into Qatar is possible without having to pay customs, but one must be aware of the procedures and regulations that must be followed in order to do so correctly. Qatar has a very specific set of laws and regulations regarding the import of goods and materials, and it is important to be familiar with these laws before attempting to import any items.

The first step in successfully importing Super Duplex Plate into Qatar is to obtain an import license from the Ministry of Economy and Commerce. This license allows businesses to import goods and materials into the country without having to pay customs. Once a business is granted an import license, they must then provide the necessary documents to the Qatar Customs Department in order to complete the import process. These documents include an invoice, a packing list, and any additional documents that may be required by the customs department. Once all of the documents are submitted and approved, the goods and materials can be imported into Qatar without having to pay customs
