Aatir Steel, located in Cairo, Egypt, has built a solid reputation as a reliable manufacturer and supplier of high-performance Alloy Steel Grade B7 Bolts. These bolts are crafted to provide outstanding strength, durability, and reliability, making them perfect for tough industrial applications. Adhering to ASTM A193 standards, Aatir Steel’s B7 bolts are specifically designed to thrive in high-temperature and high-pressure settings, ensuring consistent performance in both structural and mechanical systems. With rigorous quality control and precise manufacturing techniques, Aatir Steel guarantees that each bolt meets international standards, making them a go-to choice in industries like oil and gas, petrochemical, power generation, and heavy machinery.
Alloy Steel Gr B7 Bolts are composed of chromium-molybdenum steel, typically featuring a chemical makeup of 0.37–0.49% carbon, 0.75–1.00% manganese, 0.15–0.25% molybdenum, and 0.80–1.15% chromium. These components significantly boost the bolt’s tensile strength, hardness, and resistance to heat and corrosion. Grade B7 bolts boast a minimum tensile strength of 860 MPa and a minimum yield strength of 725 MPa, along with good elongation and reduction of area, making them well-suited for high-stress applications. They maintain their mechanical integrity even under extreme conditions, such as high temperatures and chemical exposure, ensuring long-lasting performance and safety.
