SA 193 Gr B8C Hex Bolts and UNS S34700 B8C Threaded Rod manufacturer and exporter in India

Buy ASTM A193 Grade B8C Bolts for threaded fastening system in customized sizes, shapes in superior quality that is being manufactured by the support of our highly qualified and experienced technical team. A193 B8c material is known for being a corrosion resistant grade. It is useful in those applications which demand that high tensile strength and the ability to withstand high temperature. SA 193 Gr B8C Hex Bolts are simply bolts that have a head on them, which is shaped in the form a hexagon, and usually have a washer style shoulder on them. It is also known as hex cap screws; fasten wood to wood or metal to wood. ASTM A193 B8C Hex Head Bolt is used to facilitate the application of wrenches to be used to torque the bolts for them to be tightened or loosened as desired. It can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. UNS S34700 B8C Threaded Rod is a fastener and functions, thanks to the threading, which causes a tightening action from the rotational movement. The threading on the rod helps other fixings like nuts and bolts to effortlessly screw or fasten to it.  It can only be hardened by cold working and it is non-magnetic in the annealed condition. It is a stabilized austenitic stainless steel with an addition of columbium and tantalum. The columbium helps to make a stabilized type of stainless steel which is resistant to chromium carbide precipitation. This type of product is therefore recommended for parts fabricated by welding which cannot be subsequently annealed or for parts which must operate in service between the range of 800 - 1600 °F.
