Many people use steel and stainless steel, perhaps stainless steel welding wire to make cheap resistance heating elements.

You don't specify diameter. I am assuming it is the same. However, the larger the wire the lower the resistance. Temperature affects resistance. The hotter the wire, the higher the resistance. You also don't specify the layout of the wire. For example you could make a coil or choke with one wire.
R = (density)(Length)/(Area) Unit of resistance is Ohms.
The answer depends on the material and thickness of the wire.
The answer depends on the cross sectional area of the wire. This is not given.
This is called ductility.
