Operating from the heart of Amman, Jordan, Yazan Steel has built a strong reputation as a dedicated manufacturer and supplier of essential industrial components. We are proud to be a trusted source for high-strength Alloy Steel Grade 8.8 Fasteners, providing a critical link in construction and manufacturing projects across the region. Our commitment lies in delivering reliable, robust fastening solutions that meet the exacting demands of our clients, ensuring integrity and safety in every bolt, nut, and screw that bears our name.
The strength of these Grade 8.8 fasteners comes from a carefully balanced composition, primarily carbon and boron steel, which is enhanced through a controlled heat-treatment process. This gives them a minimum tensile strength of 800 MPa and a yield strength of 640 MPa, a significant step up from lower grades. This means they offer a powerful combination of high strength and good ductility, allowing them to withstand substantial loads and stresses without fracturing, making them a dependable choice for demanding situations.
