Welcome to Desta Steel, a trusted name in manufacturing and supply right here in Addis Ababa. We specialize in providing robust and reliable fastening solutions for Ethiopia’s growing infrastructure and industrial sectors. Our focus is on the Alloy Steel Gr 8.8 Washer, a critical component engineered to meet the demanding requirements of modern construction and machinery. Manufactured with precision and adhering to strict quality standards, this washer is a testament to our commitment to strength and durability.
The strength of the Gr 8.8 washer comes from its specific composition, primarily carbon and boron steel, which is carefully heat-treated. This process gives it a defined minimum tensile strength of 800 MPa and a yield strength of 640 MPa. Essentially, this means the washer is incredibly strong and resistant to permanent deformation under heavy loads, providing a reliable and secure performance in the most challenging environments.
