WebGalling is a physical/chemical adhesion of the sheet metal to the tool surface. The severity of the galling depends on the surface finish and chemical composition of the material and the tool steel and involves the friction and sliding contact between the tooling and the material. ... Higher strength steels lead to greater demands on the wear ... WebGalling occurs when two metals are in sliding contact. The two surfaces become interlocked due to their crystal structure. Under the tensile force, deformations of the surface can occur, which we perceive as scratches. Galling can be prevented by using sufficient lubricant. oracle 19c rootcrs.pl
