Alloy Steel B7 Stud Bolts are crafted from chromium-molybdenum steel, featuring a typical chemical makeup that includes carbon (up to 0.49%), manganese, phosphorus, sulfur, silicon, chromium (0.75–1.2%), and molybdenum (0.15–0.25%). These bolts are known for their impressive mechanical strength, achieving a minimum tensile strength of 125 ksi (860 MPa) and a yield strength of 105 ksi (720 MPa). They also maintain a hardness level below 35 HRC to ensure ductility. B7 stud bolts undergo heat treatment to enhance toughness and performance, making them perfect for high-pressure and high-temperature applications.
