Question 1

Is Monel 400 Coil easy to weld, and does it require pre or post weld heat treatment?

Accepted Answer

Monel 400 typically has been said to be easy to weld through the use of standard practice such as TIG, MIG and shielded metal arc. It is a solid solution alloy, which implies that it does not need preheating or after welding heat treatment to attain acceptable properties. Before welding, the immediate environment will however have to be carefully cleaned of any pollutants.

Question 2

What manufacturing challenge makes Monel 400 difficult to precisely form into a coil?

Accepted Answer

The main challenge is that it has high rate of work hardening and quickly enhances the yield strength of the material when it is bent or drawn in a coil. This demands low formation rates, high powered equipment, and numerous steps of in between annealing. Lack of control over work hardening results in cracking and or extreme tool wear.

Question 3

What property gives Monel 400 Coil unique resistance to high velocity seawater?

Accepted Answer

Monel 400 has a very low corrosion rate in rapidly moving seawater also due to the tendency to quickly embed tenacious surface oxide film. This steady film offers excellent resistance to erosion as well as cavitation corrosion which is a typical failure mode of most stainless steels.
