When the screw Galling or bite?

2021-12-08

stainless steel has good ductility, but its hardness and carbon steel have a certain gap. In fact, the hardness of 316 authenticate stainless steel A4-80 can only reach 8.8, which is equivalent to the hardness of carbon steel.

When the Screw Galling, or bite, creates a thin oxide layer on the metal's surface when it is damaged, preventing further corrosion. When the stainless steel fasteners are locked, the pressure and heat generated between the teeth will destroy and erase the chromium oxide layer between the teeth, making the metal teeth directly blocked/shear, and then the phenomenon of adhesion, will make the stainless steel fasteners completely locked, can not be removed or locked.
