We offer These ASTM A 453 GR 660 Class C Fasteners as per DIN, ISO, JIS or ANSI Standard.
ASTM A 453 GR 660 Class C Fasteners 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 C fasteners generally exhibit good resistance to galvanic corrosion due to their alloy composition, which includes corrosion-resistant elements like nickel and chromium. Proper material selection and surface treatments can further enhance their resistance in environments prone to galvanic corrosion, such as marine settings. Regular maintenance and adherence to industry standards also contribute to maintaining their corrosion resistance over time.
