Once age-hardened, A286 nuts are noted for their exceptional strength, creep resistance, and oxidation resistance at high temperatures. As a result, A286 nuts can endure temperatures above 1300°F (700°C) at room temperature. Iron, nickel, and chromium make up the stainless steel alloy A286 (1.4980) nuts, commonly known as Alloy 660 nuts. A286 nuts are also corrosion resistant to some extent. They have exceptional oxidation resistance in high-temperature exhaust streams, reaching temperatures of up to 1500°F (815°C). They should not be used in strongly acidic circumstances. A286 nuts are outstanding in terms of mechanics. Their stress and rupture resistance is significantly greater than that of other stainless steel grades, particularly stainless steel grade 304. They are easily employed in low-stress, high-temperature applications. They have the necessary properties to show resistance to sensitization and intergranular corrosion. They can't attract others. Non-magnetic nuts are categorized as A286.

The A286 nut is available in several sizes and forms. Because of the properties of Alloy A286, these nuts are typically encountered in high-temperature engines. A286 is ideal for cryogenic equipment that does not require magnetic properties because it is non-magnetic. We also offer A286 fasteners that meet the ASTM A453 Grade 660 specification for essential high-temperature applications, ensuring appropriate tensile and stress rupture qualities. A286 nuts are used in a variety of industries, including aerospace, chemical processing, expansion joints, food processing, petroleum refineries, and waste treatment.
