Alloy201Process performance：

Welding process: In the welding process, the welding speed, weld penetration and back width ratio are greatly affected by low-power welding, while the weld forming is stable under high-power conditions.

Heat treatment process: The heat treatment process of Alloy201 needs to pay attention to the niobium content and segregation degree in the alloy, as well as the selection of the ingot diameter to avoid excessive elemental segregation.

Plastic process:

Pure nickel is also suitable for heavy cold working such as spinning and winding due to its low work hardenability.
