sSteel studbolt grade b7 size 1/2 inch 8 centimeter
The B7 steel stud bolt size 1/2 inch 8 cm is manufactured from chromium-molybdenum alloy steel and produced according to ASTM A193 standards. The total length of the component is 80 millimeters, with a nominal thread diameter of 12.7 millimeters. The threads are designed in UNC form with a 13 TPI pitch, ensuring compatibility with class 2H industrial nuts. The ultimate tensile strength of this stud bolt is approximately 860 megapascals, while its yield strength is around 720 megapascals. These properties allow the component to perform reliably under high temperature and heavy mechanical stress conditions.
The surface of the B7 stud bolt size 1/2 inch 8 cm is heat-treated with precise hardening, achieving a hardness level of approximately 35 HRC. The surface is coated with galvanization or phosphate to enhance resistance against corrosion and oxidation. This stud bolt is widely used in oil, gas, petrochemical, and pressure vessel applications. It is fastened using class 2H hex nuts, with a standard tightening torque of about 75 newton-meters.
