Beside this, what is galling in stainless steel?
Galling is a form of wear due to excessive friction between two moving surfaces. This can happen when installing a bolt into a threaded hole, or a fitting into a pump housing. It is usually prevalent with stainless steel parts but can happen with any material.
Additionally, why do stainless steel threads gall? Essentially, galling is a form of severe adhesive wear. Galling happens during installation to fasteners made of alloys such as stainless steel, aluminium and titanium. While the fastener is being tightened, pressure builds between the thread surfaces and breaks down the protective oxide coatings.
Furthermore, how do you stop galling?
- 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.
What is anti galling compound?
Anti-seize compounds are used to coat threads on fasteners and other threaded metal parts to prevent galling or sticking when the parts are mated together.
