Filiz Steel, based in Istanbul, Turkey, is a trusted name in the manufacturing and supply of top-notch fasteners, including Alloy Steel Gr 7 Stud Bolts. These bolts are crafted to meet ASTM A193 standards, making them perfect for low-temperature and high-pressure settings. Thanks to our cutting-edge manufacturing techniques and rigorous quality control, Filiz Steel guarantees that every Gr 7 stud bolt provides reliable performance, impressive mechanical strength, and precise dimensions for essential industrial uses in the oil & gas, petrochemical, and power generation industries.
Our Alloy Steel Gr 7 Stud Bolts are made from low-temperature carbon steel and undergo a quenching and tempering process to enhance their mechanical properties. They boast remarkable toughness even in sub-zero conditions, typically achieving a minimum tensile strength of 515 MPa and a yield strength of 415 MPa. While they meet the ASTM A193 Grade B7 criteria, these bolts are specifically tested for impact resistance in low temperatures, making them ideal for cold service applications. They are often paired with ASTM A194 Grade 7 nuts.
