Alloy 20 fasteners are robust components crafted from a blend of nickel, chromium, and molybdenum, creating a highly durable and corrosion-resistant material ideal for high-temperature settings or areas with significant acidity. The inclusion of copper in Alloy 20 fasteners enhances their resistance to stress corrosion cracking, adding extra protection against hydrochloric and sulfuric acids. This makes Alloy 20 fasteners an excellent option for industrial applications that demand dependable performance in challenging acidic environments.
Alloy 20 fasteners are available in a wide range of shapes and sizes, including bolts, screws, nuts, washers, and studs. These fasteners are versatile and serve various functions in industrial applications, such as joining components, sealing against gas or liquid pressure, securing items against vibration, and creating a strong connection between two parts without sacrificing structural integrity.

Alloy 20 is an austenitic alloy composed of nickel, iron, and chromium, engineered for excellent resistance to corrosion, especially in acidic environments. This alloy maintains stability even at elevated temperatures and resists chloride-induced corrosion. The presence of niobium in its composition enhances its stability, further boosting its anti-corrosive properties. With its strong mechanical and chemical characteristics, Alloy 20 is highly suitable for fabricating durable piping components.
