ASTM A453 Grade 660 Class B Nuts are durable fasteners known for exceptional durability and corrosion resistance. Made from high-performance nickel and chromium alloys, these nuts excel in harsh environments such as offshore rigs, petrochemical plants, and power plants. Meeting stringent ASTM standards, they are reliable and durable in critical components requiring secure packaging. ASTM A453 Grade 660 Class B nuts provide excellent mechanical properties and durability at elevated temperatures, making them essential for applications requiring high tensile strength and long durability under harsh operating conditions in

We offer These ASTM A 453 GR 660 Class B Nuts as per DIN, ISO, JIS or ANSI Standard.
ASTM A 453 GR 660 Class B Nuts 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.
ASTM A453 Grade 660 Class B Nuts generally exhibit good resistance to galvanic corrosion due to their alloy composition, which includes corrosion-resistant elements like nickel and chromium. These elements help form protective oxide layers that mitigate galvanic reactions when in contact with dissimilar metals. However, in environments prone to galvanic corrosion, such as marine settings, it’s advisable to employ proper material selection and surface treatments to further enhance their resistance and ensure long-term durability. Regular maintenance and adherence to industry standards also contribute to maintaining their resistance to galvanic corrosion over time.
