Nexora Metal, a leading manufacturer, supplier and exporter, provides high-quality Alloy Steel B7M Fasteners for crucial bolting applications. Alloy Steel B7M fasteners are high-strength bolting components constructed of ASTM A193 Grade B7M chromium-molybdenum alloy steel. This grade is heat-treated to reduce hardness and increase ductility. The regulated heat procedure helps to prevent sulfide stress cracking in marine operations. These fasteners are widely used in pressure vessels, valves, flanges, and high-pressure piping systems. The material handles high pressure and moderate heat with stable strength. Lower hardness improves safety in hydrogen sulfide service. The result is a reliable fastening solution for demanding plant conditions.

​

Alloy Steel B7M Fasteners are available in bolts, studs, threaded rods, nuts, and washers. We verify that the production process adheres to the ASTM A193 and ASME SA193 specifications for strength and chemical balance. Mechanical values vary with size. Tensile strength is 125 ksi for lengths up to 2-1/2 inches, while yield strength is 105 ksi, with 16% elongation and 50% area reduction. Larger diameters offer controlled strength and consistency in ductility. This equilibrium supports safe load handling under stress. marine, oil and gas, petrochemical, energy, power, refining, shipbuilding, food, aerospace and chemical industries rely on these fasteners to keep pressure joints in place.
