Product Description

 

Round Square Inconel 690 Nickel Based Alloy Tube for Pickling tank 

 

ALLOY 690 • UNS N06690 • WNR 2.4642

Alloy 690 is a high-chromium nickel alloy having excellent resistance to many corrosive aqueous media and hightemperature atmospheres. The alloy's high chromium content gives it excellent resistance to caturisation, metal dusting, oxidation and sulfidation at high temperature. In addition to its corrosion resistance, alloy 690 has high strength, good metallurgical stability, and favorable fabrication characteristics. 

Available Tube Product form

• Straight
• Seamless

Typical Applications

• Heat exchangers
• Steam Generators
• High temperature applications exposed to caustic solutions

Industries predominantly using this Grade

• Chemical processing
• Nuclear and Power
• Oil and gas

Typical Manufacturing Specifications

• ASTM B167
• Also individual customer specifications.
