Duplex plate

duplex plate

What is a duplex plate ?

Duplex is a powerful austenitic and ferritic dual-microstructure grade. The duplex plate has a chemical composition of carbon, manganese, silicon, phosphorous, sulfur, chromium, molybdenum, nickel, nitrogen, and copper. Duplex stainless steel plate has excellent corrosion resistance and tolerance in harsh environments. The plates are tolerant to crevice corrosion and pitting by chlorides. The s2205 is a common grade of the duplex grade. The duplex plate supplier subject the plates to harsh conditions and has a temperature limit below 600 degrees f. These plates can be easily welded following standard procedures.

The duplex plate material grade has excellent mechanical properties. This material has an ultimate tensile strength of 95ksi with a minimum yield strength of 65ksi. The duplex plate suppliers supply these plates with a hardness of 31 rockwell c max. These plates have a density of 7800 kg/m3 with an elastic modulus of 190gpa. The common duplex stainless steel plate application in marine systems. These plates are also common in processing equipment, chemical processing, oil and gas exploration, paper machines, etc. The duplex steel plate has a superior surface finish and tolerances.

duplex plate

Find leading duplex steel plate traders who keep one of the largest stock ranges of duplex stainless steel sheet/ strip and coil as well as read about whether the duplex stainless plate is magnetic or not.

The duplex plate is a dual microstructure of both austenitic and ferritic grades. The plates give them the best of both worlds. Thereby, the duplex stainless steel sheet can be magnetic and still have greater corrosion resistance properties.

The duplex steel plate thickness varies between 6mm to 150mm or as per the requirements of different projects. The unique duplex plate dimensions allow it to be ordered in 1000x2000mm, 1220x2440mm, 1500x3000mm, 2000x2000mm and 2000x4000mm. The duplex plate weight calculator can be utilized to calculate the weight of the plate across different systems.

The ss duplex plate is a budget friendly grade than the ss 316 specification. The lower content of molybdenum and nickel compared to the ss 316 allows it to be availed at lower prices. The duplex stainless steel plate price is priced at $3.45 per kg. The price of an ss 316 is $4.98 per kg.

The duplex steel plate has been designed with a superior chemical content of chromium, nickel, molybdenum, and other alloys. This gives the duplex stainless steel plate excellent corrosion resistance properties. The plates have good tolerance to chloride pitting and crevice corrosion occurring in the system. The duplex plate is resistant to chloride and sulfide stress corrosion cracking.

These plates have good strength allowing them to be used in harsh environments. The content of nitrogen in the duplex steel plate gives it an edge against localized and oxidizing acidic solutions. These plates have better corrosion resistance than the 300 series. The duplex shim sheet provides stability and support to different applications.

The duplex plate suppliers usually supply these plates in hot or cold rolled specifications. However, they can also be availed in normalized, annealed, or other conditions. The duplex plate price is dependent on the size, thickness, customization, or any requirements specified by the customers. A duplex stainless steel plate price is $3.89 per kg with 16-19 dirhams in the uae.

Are you searching best stocking distributor who is dedicated to offering customers stainless steel duplex plate in Dubai? Your search end here and see the impact of toughness

The impact toughness of the duplex sheets indicates the toughness of the material. This is done using the value of the impact energy absorbed during fracture under high impact pressure. The impact toughness of the duplex sheet at high temperatures up to 550 degrees f based on charpy v notch criteria of 35 ft-lbs. Generally, the duplex steel sheet should be limited to 500 degrees f to have better impact toughness.

Get the largest hot/ cold rolled duplex plate suppliers who supplied nationwide in a full range of standard and special sizes, know about duplex steel sheet rust properties as per EN 10088-2

The duplex plate has a good chemical composition and has enhanced resistance to corrosive and oxidative media. The plates are also tolerant to marine and chloride pitting or crevice corrosion. They are, however, prone to rust when exposed to temperatures above 600 degrees f.

This equipment is available in different finish types. Duplex 2b finish sheet is a common finish type. They are also available in cold drawn, 1d, 2d, no1, and various other specifications. The duplex stainless steel sheet is easily wound, allowing them to be efficiently transported. The coils can be cut in different conditions. Duplex stainless plate is designed with an array of designs and surface finishes. This allows them to add an aesthetical outlook to the grade.
