The company merges cutting-edge manufacturing technologies with strict quality control to ensure they meet international standards. Renowned for their reliability, prompt delivery, and competitive pricing, Aatir Steel is dedicated to fostering industrial growth in Egypt and beyond by offering wear-resistant solutions that are customized to meet customer needs and the challenges of demanding operational environments.
The 400 Brinell Hardness Number Sheets and Plates are specially designed alloy steels known for their outstanding wear resistance and strength. Their typical chemical makeup includes carbon (0.3–0.4%), manganese, chromium, nickel, and boron, all of which enhance hardness and toughness. These plates boast a nominal hardness of 400 HBW (Brinell Hardness Number), a tensile strength ranging from 1250 to 1450 MPa, and a yield strength exceeding 1000 MPa. With remarkable impact resistance and formability, they maintain their structural integrity even under high-stress conditions. The plates undergo heat treatment through quenching and tempering processes to guarantee consistent hardness and mechanical properties throughout the material.
