ASTM A453 Gr.660 Hex Nuts

Vision Alloys is particularly adept in offering ASTM A453 Gr. 660 Hex Nuts, premium fasteners. These nuts have great strength and corrosion resistance, meeting the exact needs of high-temperature uses. The excellent mechanical qualities of the ASTM A53 Grade 660 Hex Nut make it appropriate for usage in several sectors, including petrochemical, power generation, and others.


ASTM standards—especially ASTM A453 Grade 660—are followed in manufacturing our ASTM A453 Grade 660 Hex Nuts. A453 Grade 660 specification addresses high-temperature bolting materials and stainless steel alloys for pressure vessel flanges, valves, and fittings. The nuts follow ASME B18.2.2 dimensions as well, which specify the guidelines for heavy hex nuts. It guarantees that our goods satisfy industry criteria for performance and quality and fit other components. Several classes are included in the ASTM A53 Grade 660 specification; Class A is one of the most often utilized. Tensile strength and flexibility are rather well-balanced in this class. The ASTM A453 Gr 660 material is ideal for important uses and is meant to resist strong temperatures and hostile surroundings.


The ASTM A453 Grade 660 Chemical Composition includes a unique blend of elements that provide the nuts with excellent mechanical properties. Typically, this composition includes Nickel (24-27%), Chromium (13.5-16%), Molybdenum (1.5-3%), and other alloying elements. This specific composition ensures the material's stability and strength under high-temperature conditions, making the ASTM A453 Gr 660 Hex Nut a reliable choice for demanding applications. Due to its high strength and resistance to thermal expansion, the ASTM A453 Gr 660 Class A nuts are widely used in power plants, petrochemical plants, and other high-temperature environments. The specification of ASME B18.2.2 Heavy Hex Nuts further ensures these nuts can handle substantial stress and pressure. ASTM A453 Grade 660 Class A is ideal for applications requiring durable and reliable fastening solutions.
