A193 B7 Bolts and A193 B8M Class 2 Stud Bolts in High Pressure Conditions

ASTM A193 Grade B7 is a specification for high strength alloy steel bolting components which are intended for use under high temperature or high-pressure conditions and other special purposes. It is a standard specification that specifies typical chemical composition, mechanical properties, hardness requirements, preferred heat treatment, product marking, certification and other requirements. The oil & gas industry depends heavily on A193 B7 Bolts due to their excellent resistance to high pressure, extreme temperature and corrosive environments. These fasteners are commonly used in drilling rigs, wellhead equipment and refineries where they are critical liaison components such as pipeline flanges, pressure vessels and heat exchangers which are secured by them.

ASTM A193 B8M Stud Bolts are made of stainless steel with an austenitic microstructure and have a special thread design which enables these bolts to be used in both tension and compression. In contrast to typical threaded fasteners, these stud bolts with special thread pattern are capable of absorbing shock loads more effectively. Being a part of ASTM A193 specification, these stud bolts must meet certain minimum requirements for industrial use. One of the key advantages of A193 B8M Class 2 Stud Bolts is their corrosion resistance that allows them to be used even in the most severe environments. They are ideal for marine, off shore and chemical industries where contact with salt water or corrosive chemicals is a constant. In addition these stud bolts are highly heat resistant and can even be used safely at 1000 degrees Fahrenheit without having to sacrifice their structural strength or performance.
