The fasteners most commonly prone to galling when tightened are made of stainless steel, aluminium or titanium. Stainless steel fasteners are available in austenitic, ferritic and martensitic grades, with austenitic grades of stainless steel fasteners usually used in the industry. The stainless steel material has a chrome oxide layer, which protects it from corrosion.
