ASTM A453 Grade 660 includes several types of fasteners, including hex bolts. These hex bolts are made from alloy steel and are designed to withstand elevated temperatures and corrosive environments. The Grade 660 designation specifically refers to the alloy composition and mechanical properties of the material.


Here are some key characteristics of ASTM A453 Gr. 660 hex bolts:

  • Material: ASTM A453 Grade 660 hex bolts are typically made from a special stainless steel alloy known as UNS S66286 or A286. This alloy is known for its high strength and excellent resistance to oxidation and corrosion at high temperatures.
  • High-Temperature Application: These bolts are suitable for use in high-temperature environments, such as those found in gas turbines, jet engines, and industrial furnaces.
  • Corrosion Resistance: A453 Gr. 660 hex bolts are highly resistant to corrosion, making them suitable for use in marine and chemical processing applications.
  • Mechanical Properties: The material has high tensile strength and excellent creep resistance, making it suitable for applications where mechanical strength is crucial.
  • Heat Treatment: ASTM A453 Grade 660 hex bolts are typically heat-treated to achieve the desired mechanical properties.
  • Sizing: Hex bolts are typically available in various sizes to suit different applications and requirements.
