No... it's simply been over-tightened. The SS has galled a bit, and will require added effort to separate.
Make sure it's clean and dry, and use a couple of patterned rubber, "jar lid gripper" sheets - it will unscrew, unless you've squeezed hard enough to distorted the lower tube, then you'll need to "make it round" again. Best to leave the tube on the atty base - gives you a bit extra to hold onto.
