ASTM A193 Grade B7 Bolts

ASME SA193 B7 Stud Bolt & A193 Gr B7 threaded rod manufacturer in India

A193 B7 material is a standard material specification for chromium-molybdenum alloy steel fasteners for use in high tensile, high temperature and special purpose applications. SA 193 B7 material is widely used for fasteners specifications and which is commonly found in bolting, piping, valves, fitting, flanges and pressure vessels. SA 193 gr b7 fabricated from medium carbon alloy steel that go through a heat treating process in order to develop its strength. ASTM A193 Grade B7 Bolts is considered for applications up to 450°C due to the heat treated chromium molybdenum steel. B7 hex bolts are bolts with external threading and a hex head designed to be driven by a wrench. It can be fully or partially threaded, and are available in hex cap. ASTM A193 gr B7 bolts has a minimum tensile strength of 100 ksi, yield strength of 75 ksi and maximum hardness of 35 HRC.

ASTM A193 grade B7 threaded rod is designed to be used in tension. It is ideal for a tightening action from the rotational movement. It allows other fixings like nuts and bolts to easily screw or fasten to it. A193 B7 Threaded Rod is also known as stud. It is threaded on both the ends and it is relatively long rod. Its thread may extend along the complete length of the rod. A193 Gr B7 Bolts are built to the requirements of numerous specifications and material design properties. A193 B7 Bolts are manufactured from chromium-molybdenum steel and are quenched and tempered to develop the desired mechanical properties. Grade b7 bolts is the most common grade used in construction. B7 Stud achieves its strength through the process of heat-treating where it is quenched and tempered at 1150 degrees F. B7 Studs is in high demand due to its excellent heat resistance and tensile strength.

ASTM A193 grade B7 stud bolts are externally threaded fasteners without a head which is been used with two nuts on either side, exchanging a regular "bolt & nut" assembly. A193 B7 Stud Bolt is prominently used in flange connections depending upon its threading pattern and design. There are different types of Stud Bolt ASTM A193 Grade B7 such as tap end stud bolts, continuous threaded stud bolts, double end stud bolts, welding stud bolt and flange stud bolts. B7 Nuts is a standard material specification for high tensile nuts which is been made from carbon steel. b7 2h Nuts is been produced by the method of hot forging, cold forging or machining from heat treated bar stock.
