B7 stud bolt

Grade B7 steel studs have a minimum tensile strength of 1050 MPa and a yield strength of 860 MPa, designed for high-pressure applications. This grade is made from chromium-molybdenum alloy steel, enhancing mechanical and thermal resistance up to 425 degrees Celsius. The thread diameter and stud length comply with ASTM A193 standards, with a surface hardness range of 240 to 280 Brinell. B7 studs can withstand high torsional and tensile loads and are widely used for pressure connections in the oil, gas, and petrochemical industries.

The manufacturing process of Grade B7 steel studs includes quenching and tempering heat treatments to achieve an optimal microstructure. This process ensures high hardness and strength, preventing premature failure. Additionally, precise control of dimensions and threads according to ASME B16.5 standards guarantees perfect compatibility with nuts and fittings. Using B7 studs increases the durability and safety of high-pressure connections, providing reliable performance under harsh environmental conditions.
