Frequently Asked Questions

Quick answers to common queries about Duplex 2205 Plates.

Plates with a polished or premium surface finish cost a bit more because extra processing goes into making them smooth, shiny, and precise.
Custom sizes mean extra cutting, handling, and precision work, so naturally the cost goes up compared to standard plates.
Absolutely—nickel, molybdenum, and chromium prices can swing, and since Duplex 2205 relies heavily on these alloys, your plate costs can vary too.
Thicker plates use more material and weigh more, so both production and shipping costs increase, making them pricier.
Bigger plates aren’t just heavier—they also require more material and careful handling, so the price naturally goes up.
These plates are perfect for chemical plants, marine structures, oil & gas, and desalination equipment because they resist corrosion and handle tough conditions.
Thanks to its high chromium, molybdenum, and nitrogen content, Duplex 2205 stands up to pitting and stress corrosion cracking, even in salty environments.
A smooth, polished finish is key for hygienic setups, filtration, and any application where corrosion resistance and cleanliness matter.
The heavy use of nickel, molybdenum, and chromium makes the raw material more expensive, which directly affects the price of the plates.
