Majid Fasteners is the well-established manufacturer and distributor of high-end industrial fasteners in Dubai, UAE, that has a record of producing high-quality products in line with the strict international standards. We specialize in ASTM A453 Grade 660 Class C stud bolts which are high-performance fasteners that are used in extreme temperature and pressure environments in the power generation, petrochemical, and refinery industries. As highly quality conscious company, precision engineer and customer satisfaction company, Majid fasteners would guarantee quality, structural stability and durability of fasteners that facilitate safe and efficient operation of critical industrial systems.
ASTM A453 Grade 660 Class C Stud Bolts are high-strength Austenitic, Property 840 graded alloy iron stud bolts, which are similar to A-286 alloys. The material composition for these stud bolts is normally Nickel (24% to 27%), Chromium (from 13.5% up to 16%), Molybdenum (from 1% to 1.5%), Titanium (1.9% to 2.35%), Vanadium and Boron (in very small quantities), with Iron being the primary alloying material. These alloying materials provide this stud bolt material with exceptional sold performance characteristics of high-temperature strength and oxidation resistance, as listed above in the mechanical property chart for grade 660 stud bolts. In addition to improved strength and oxidation resistance, these stud bolts have an ultimate (maximum) tensile strength of 760 N/mm2, a yield strength of 585 N/mm2 and a high level of ductility, elongating approximately 15% under a tensile load with good creep resistance, providing exceptional performance in high-stress and high-temperature environments.

Grade C stud bolts can be used in applications that require high temperature and pressure, where durability and stability over time are required. ASTM A453 Grade 660 Class C stud bolts are frequently used. They are typically applied to the gas and steam turbines, boilers, heat exchangers and high temperature flange. These fasteners are used in industries like power generation, petrochemical, oil and gas, as well as chemical processing where the equipment is subjected to the extreme thermal stress in both equipment and industries. They are also very advantageous in taking up pressure vessels, reactor assemblies, refinery units and other demanding environments due to their good creep resistance, oxidation stability and mechanical strength that ensures safe and efficient operations of industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
