Open coil (032) has a typical "spring" look and is used to open space between teeth. 

Providing heavier teeth moving forces when compressed, compared to nickel titanium coils

A length of coil that is one to three millimeters longer than the interbracket distance is cut, inserted over the archwire, and tied into place with steel ligatures on either end to resist the rotational moments created.

Open coil may be "packed" or compressed in the anterior segment on Nickel-Titanium archwires, but should only be used on a stainless steel archwire (which is more rigid) when used in the posterior.

 Open Coil may be compressed in any part of the arch, anterior or posterior with 18x25N as the supporting archwire. 

Activation of nickel chrome / stainless steel coils should be 25% of the original length. Therefore, if compressing nickel chrome / stainless steel open coil between brackets 8mm apart, a 10mm piece of coil would be used. 

You would also use nickel chrome / stainless steel open coil to move "several teeth", such as when opening a space in the middle of the arch.
