All military/aerospace stainless steel machine screws require passivation: the process used to assure removal of contaminants, particularly free-iron, from the surface of stainless steel and facilitate the formation of chromium oxide. By controlling the passivation process on-site, Pilgrim Screw is able to complete and deliver your orders even faster!
With our state-of-the-art passivation room upgrade, we can now offer Type 8 (Medium Temperature, High Nitric Acid Concentration) passivation as well as the Type 6 (Low Temperature Nitric Acid) passivation we’ve always provided.
What does this mean for our clients?
• Faster turnaround on stainless steel orders
• Lot traceability always maintained because we never commingle lots
• All individual lots tested to AMS-STD-753 Method 100 Water Immersion Test
• Full conformance to AMS-2700 standard (replaces AMS-QQ-P-35), which is the prevailing finish specification for military & aerospace fasteners made from stainless steel.
