What are Alloy 20 Fasteners?
Alloy 20 Fasteners are corrosion-resistant fastening components manufactured from Alloy 20, a nickel-iron-chromium alloy containing copper and molybdenum. They are specially designed for applications involving sulfuric acid, phosphoric acid, chlorides, and other aggressive chemicals where conventional stainless steel fasteners may fail.
These fasteners include bolts, nuts, screws, studs, washers, threaded rods, anchor bolts, and customized fastening solutions available in various sizes and specifications. Alloy 20 Fasteners are widely used in chemical processing plants, pharmaceutical industries, petrochemical facilities, food processing units, heat exchangers, and other industrial applications requiring superior corrosion resistance and mechanical strength.
