Industrial ASTM B444 Heat Exchanger Tubing
ASTM B407 Nickel Alloy Tube for Heat Exchanger
Application:
1) Evaporation tank, acid and alkali industrial machine in petrochemical production, catalytic regenerator,heat exchanger.
2) The production and use of corrosive alkali metals, especially in environments where sulfides are used,
3) Jet engine components, supplemental components of turbojet engines, etc.
Inconel 600 alloy is ni - cr - iron base alloy solid solution strengthening, has good resistance to high temperature corrosion and oxidation resistance, excellent hot and cold processing and welding performance, under 700 ℃ has a satisfactory heat intensity and high plasticity.Alloy can be strengthen through the cold work, also can use resistance welding, welding or soldering connection.
