What is super duplex plate and its grades ?

Super duplex is a high performing austenitic stainless steel grade that possesses superior strength and corrosion resistance. The Super Duplex Plate is ideally used in industries where they are exposed to highly corrosive environments including seawater and different types of chemicals. The Super Duplex cold-rolled plates are available in different grades with varied chemical and mechanical properties.

  • 2507 is one of the most corrosion-resistant grades available. It also possesses superior impact toughness up to -46 °C.
  • 4501 shows high performance in terms of rust resistance, strength and durability.

Is it possible to weld Monel and super duplex stainless steel plate?

Monel and Super Duplex Stainless Steel Plate can be welded but the process should be carried out carefully or galling may occur. It is crucial to select the right welding technique and compatible filler material for getting a balanced joint. Also, the Monel and Super Duplex hot-rolled plate should be cleaned and prepared properly to ensure the weld quality.

As both materials have different thermal conductivity and heat expansion coefficients, hence controlling the heat input properly is quite crucial. Contact Regent Steel & Engineering Co. for welding Monel and Super Duplex clad plate, as they have experienced welders who have worked with both materials for several years.

Which one is superior, UNS S32750 or UNS S32760 sheet?
  • UNS S32760 offers higher corrosion resistance in different aggressive media. They also show better resistance to pitting and crevice corrosion. UNS S32760 Super Duplex annealed plate can withstand stress corrosion and erosion cracking.
  • UNS S32750 has higher strength and impact strength too. The UNS S32750 Super Duplex foil is used in applications where a balance of corrosion resistance and strength is required.

What is the purpose of a super duplex sheet?

The Super Duplex Sheet shows good resistance to corrosion and chloride-rich environments. Thus, they can be used in chemical processing, desalination plants and the oil & gas industry. The high strength of the Super Duplex Stainless Steel Sheet makes it perfect for various structural applications that require high load bearing. Also, the sheets made of Super Duplex Plate Material are used in heat exchangers for the pulp & paper industry.

Is it expensive to buy a super duplex steel plate? why ?

Yes, the super duplex steel plate is more expensive than the standard stainless steel grades. This is because of its alloying elements which has higher content of material like chromium, nickel, molybdenum, etc. They are manufactured through complex processes which also contributes to the higher Super Duplex Price Per Kg. The raw material has limited availability and they are difficult to weld and fabricate. Also, their high demand and use in specialized applications have increased their price.

Is there corrosion resistance in super duplex plate?

The super duplex plate suppliers promote the products for their excellent corrosion resistance properties. They have a high chromium content which leads to the formation of a passive oxide layer that resists further corrosion. The molybdenum enhances pitting and crevice corrosion resistance. Their dual-phase microstructure and presence of nitrogen also increase the mechanical properties. The super duplex material shows good resistance in acidic and alkaline environments along with chloride ion related stress corrosion cracking.
