Asme Sa 193 Grade B8 Cl2 Stud manufacturer in india guaranteed best price in india
ASTM A193 Grade B8 Class 2 Bolts are high strength fasteners that are used in various industrial applications. Viha Steel & Forging is a leading manufacturer of the different types of the B8 fasteners. There are two classes. The Astm A193 B8 Class 2 Bolts are strain hardened and are used in high stress applications such as petroleum, oil and gas, chemical and construction applications.
The fasteners are made up of 304 austenitic stainless steel grade material. The B8 Class 2 Stud and other fasteners have minimum tensile strength ranging from 75ksi to 125ksi depending on the different sizes. The smaller sizes usually have high strength. The astm a193 b8 class 2 torque chart provides the different strength and capacities of different types, shapes and sizes of the different fasteners in this grade. There are different types such as threaded rods, screws, washers and others. The ASTM A193 B8 Cl2 has good general corrosion resistance.
The material is also one of the most used because of the low cost of the material. It is the most used because of the balanced ductility, strength and corrosion resistance. The ASTM A193 B8 Class 2 Fasteners can be seen in domestic, industrial and commercial applications such as water supply, chemical, petroleum, power plant, heat exchanger and many other applications. Please feel free to contact us for more information on the different types such as the A193 B8 Class 2 Stud Bolts and others.
