What is galling in stainless steel?
Thereof, what causes stainless steel galling?
Galling is adhesive wear that is caused by microscopic transfer of material between metallic surfaces, during transverse motion (sliding). Threaded inserts of hardened steel are often used in metals like aluminium or stainless steel that can gall easily.
Furthermore, why do stainless steel bolts seize? Fasteners like stainless steel, aluminum, and titanium produce their own protective oxide film to prevent corrosion and are especially prone to galling. The film breaks down under installation pressures and the resulting metal-to-metal friction causes heat that fuses and can seize the metal.
Likewise, people ask, how do you prevent galling on stainless steel bolts?
- Slow Down Installation Speed.
- Don't Use Bolts to Pull Joints Together.
- Use a Lubricant.
- Avoid Damaged or Dirty Threads.
- Use Extra Care With Lock Nuts.
- If a Fastener Begins to Bind: STOP.
