Jim, The door torsion bars are made of stainless steel. The brown spiral lines are a result of the Cryogenic manufacturing processing. These lines are easily removed using a multipurpose cleaner such as Westley's Bleche-White. Keep in mind that scratching the torsion bar with a sharp instrument could cause the bar to fracture.
