Alloy 20 nuts are fasteners made from Alloy 20, a super-austenitic stainless steel known for its excellent resistance to corrosion, acid attacks, and pitting. These nuts are commonly used in industries with harsh environments, such as chemical processing, food processing, and pharmaceutical applications. Alloy 20 nuts provide a strong and reliable fastening solution, especially in situations where standard stainless steel or other materials may not offer sufficient corrosion resistance.

Alloy 20 Nut applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Yes, Alloy 20 nuts can be recycled after use. The stainless steel composition of Alloy 20 allows it to be recycled and repurposed, contributing to sustainable practices in the metal industry.
Alloy 20 nuts are generally not recommended for cryogenic applications due to their reduced toughness and impact strength at extremely low temperatures. Specialized alloys with better cryogenic properties are typically preferred for such demanding conditions.
Alloy 20 nuts can be used for underground applications where corrosion resistance is crucial. Their ability to withstand harsh environments and resist corrosion makes them suitable for securing components in underground installations subject to soil moisture and chemical exposure.
Considerations for installing Alloy 20 nuts include ensuring proper torque values are used to prevent over-tightening or under-tightening, verifying compatibility with mating fasteners and components, and implementing suitable corrosion-prevention measures to maintain the integrity of the fastening system.
