ASTM A453 Grade 660 Class A/B/C/D Fasteners

ASTM A453 Gr 660 Stainless Steel Bolt, ASTM A453 660 Class A/B/C/D Bolts, Nuts, Stud Bolts, Washers Supplier in India

Ratna Exports specialize in manufacturing high-quality Stud Bolts, Hex Bolts, Heavy Hex Bolts, Socket Head Cap Screws, Threaded Rods, Nuts, and Washers according to ASTM A453 Grade 600 Class A/B/C & D standards. Our Grade 660 Bolts are available in sizes ranging from 3/8″ to 4″ in imperial measurements and up to M100 in metric sizes. We offer customization upon request for larger bolts based on specific requirements and drawings. We maintain a stock of premium and surplus bar stock in Grade 660 (UNS S66286; Alloy A286) to facilitate quick manufacturing and shorter delivery times. Our ASTM A453 Grade 660 Class A/B/C/D Bolts come with EN 10204 Type 3.1 Material Test Certificates (MTC), ensuring traceability and quality assurance. Additionally, we provide a Rupture Test Facility for sufficient quantity orders. ASTM A453 Grade 660 is a specification designed for studs, bolts, nuts, and other fasteners for high-temperature applications. This grade is classified into four property classes: A, B, C, and D, each with different tensile and stress rupture properties. These fasteners are commonly used in bolting applications for boilers, pressure vessels, pipeline flanges, and valves operating at elevated temperatures. ASTM A453 Grade 660 material is chemically equivalent to ASTM B638 Grade 660 stainless steel alloy, also known as Alloy A286 and UNS S66286. It undergoes heat treatment to achieve the properties specified in the ASTM A453 standard.
ASTM A453 Grade 660 Class A/B/C/D Fasteners
Typically, A453-660 Class C bolts are manufactured in sizes ranging from 3/8″ to 4″ in imperial units, while in metric terms, A453 Gr 660 nuts are produced up to size M100. However, if buyers require larger-sized A453 Gr 660 bolts, they can be custom-made upon request. A453 660 Class D specification fasteners are precipitation hardening, austenitic stainless steel components designed for high or elevated temperatures, reaching up to 1300°F or 704°C. At elevated temperatures, A453 Gr 660 Class D fasteners exhibit enhanced properties such as high tensile strength and excellent creep strength. Additionally, they offer good corrosion resistance for various applications. The ASTM A453 Gr 660 Stainless Steel Bolt Specification covers high-temperature bolting with expansion coefficients comparable to austenitic stainless steel. These fasteners are primarily intended for special engineering applications, including those in industries involved in oil production and infrastructure projects.
