Known for their precision engineering and impressive performance, Sayed Steel serves a variety of industries, providing products that adhere to strict international standards. Their Alloy Steel Gr 8.8 Fasteners are crafted for durability, reliability, and exceptional resistance to wear and corrosion, ensuring they perform well even in tough conditions. Thanks to their advanced manufacturing techniques, thorough quality control, and a strong commitment to customer satisfaction, Sayed Steel has become a trusted ally for industrial and construction projects that need reliable fastening solutions.
The Alloy Steel Gr 8.8 Fasteners from Sayed Steel are made from medium carbon alloy steel and are heat-treated to achieve the best possible strength and hardness. These fasteners typically include carbon, manganese, chromium, and molybdenum in carefully controlled amounts, which boosts their tensile strength and wear resistance. With a nominal tensile strength of 800 MPa and a yield strength of 640 MPa, they provide excellent load-bearing capabilities. The material undergoes quenching and tempering, which enhances toughness, fatigue resistance, and reliability under high-stress situations. These mechanical properties make them perfect for heavy-duty fastening tasks in both industrial and construction fields.
