The B7 stud bolt is a threaded fastener made from chromium-molybdenum alloy steel ASTM A193 Grade B7, designed for high-temperature and high-pressure applications. It has a minimum tensile strength of 125 ksi approximately 860 MPa and a minimum yield strength of 105 ksi about 725 MPa. Its surface hardness ranges from 24 to 35 HRC and it is manufactured in various heat-treated classes. The B7 stud bolt typically features a Unified 2A thread and is paired with a 2H heavy hex nut. It is produced in accordance with international standards such as ASME B18.31.2 and ASTM A193, and is commonly used in oil, gas, petrochemical, and power generation industries.
The operating temperature range for a B7 stud bolt is from minus 29 to plus 427 degrees Celsius, ensuring reliable performance under extreme thermal conditions. It is available in standard diameters from 1/4 inch to 4 inches with custom lengths upon request. Surface finishes include hot-dip galvanizing or black oxide coating to enhance corrosion resistance. Dimensional tolerances are defined based on ANSI/ASME B1.1 standards. For critical applications, non-destructive tests such as UT or MPI are also performed. Due to its high strength and mechanical stability, the B7 stud bolt is recommended for high-pressure operational environ
