The B7 standard under ASTM A193/A193M specifies alloy steel and stainless steel bolt materials for high-temperature applications in pressure vessels, valves, flanges, and fittings. These screws feature a minimum yield strength of 723.45 MPa (551.20 MPa for B7M) and elongation of 16% (18% for B7M), with maximum hardness of HRC35 (HB235). The material is chromium-molybdenum alloy steel, equivalent to domestic 40CrMo.
Used in high-strength applications like engines and heavy-duty machinery for their superior support area and anti-loosening performance.
Essential for connecting mechanical parts, circuit boards, engines, transmissions, and building structures across various industries.
Connects power generation equipment and transmission lines in the energy sector.
Provides structural connections in building projects, shipbuilding, and petrochemical equipment for enhanced safety and stability.
B7/B7M screws meet ASTM A193/A193M standards with minimum tensile strength of 861.25 MPa (689.00 MPa for B7M). The chromium-molybdenum alloy steel construction (equivalent to 40CrMo) ensures durability in high-temperature environments.
