What are ASTM A453 Gr 660 Heavy Hex Nuts?
ASTM A453 Gr 660 Heavy Hex Nuts are heavy-duty nuts widely used in high-temperature and high-pressure applications. These nuts are made of a heat-resistant alloy called Inconel 660, which has high strength and excellent resistance to oxidation and corrosion.
The heavy hex shape of these nuts provides a better grip and a secure hold.
Applications of ASTM A453 Gr 660 Heavy Hex Nuts
These nuts are used in various industrial sectors like marine, petrochemical, oil and gas, and power generation. Due to their ability to sustain high temperatures and pressure, these nuts are often used in boilers, heat exchangers, turbines, and other machinery under extreme conditions.
These nuts are also used in offshore drilling and production, where high tensile strength and corrosion resistance are crucial.
Advantages of ASTM A453 Gr 660 Heavy Hex Nuts
The key advantage of ASTM A453 Gr 660 Heavy Hex Nuts is their high-temperature and high-pressure resistance. They have excellent creep and stress rupture strength, making them ideal for heavy machinery and infrastructure use.
The Inconel 660 alloy has good corrosion resistance, making these nuts suitable for harsh environments, including marine applications. Their heavy hex shape provides a more oversized surface area, allowing for better gripping and easier tightening.
