Alloy Feature

Usage of Duplex 2507 should be limited to applications below 600° F (316° C). Extended elevated temperature exposure can reduce both the toughness and corrosion resistance of alloy 2507.

Duplex 2507 possesses excellent mechanical properties. Often a light gauge of 2507 material can be used to achieve the same design strength of a thicker nickel alloy. The resulting savings in weight can dramatically reduce the overall cost of fabrication.

Application

Desalination Equipment.
Chemical process pressure vessels, piping and heat exchangers.
Marine Applications.
Flue Gas Scrubbing Equipment.
Pulp & Paper Mill Equipment.
Offshore Oil production/technology.
Oil and gas industry equipment.
