Why do alloy steel fasteners require protective coatings like zinc or phosphate?
Alloy Steel Fasteners contain limited amount of chromium due to which it is prone to corrosion. These coatings helps prevent corrosion of these fasteners. Zinc plating is act as sacrificial coating which corrodes before alloy steel whereas phosphate improves corrosion resistance and paint adhesion.
