Galling of Stainless Steel Fasteners - PENCOM
Also known as cold welding, galling results in damaged threads, broken fasteners, weakened joints and seized bolts. Essentially, to define galling - it's a form of severe adhesive wear. Galling happens during installation to fasteners made of alloys such as stainless steel, aluminium and titanium. Visa mer Highly ductile materials, or materials which possess low work-hardening rates, are often prone to galling. For instance, austenitic stainless steels have a tendency to gall under certain conditions, though you can minimise this … Visa mer The mechanical fit should be correct – tight enough to prevent vibration and wear, but with sufficient clearance to prevent galling. Keep the contact load on the components that slide to a minimum, and the contact area, … Visa mer Opt for coarse threads with a 2A-2B fit by the Unified Thread Standards. Coarse versus fine threads give you a larger thread allowance and are more tolerant to abuse during handling. Visa mer Make sure your nut and bolt have a hardness difference of at least 50 Brinell.This is because the different alloys harden at different rates, lessening the chance of galling.
