Detailed Information

Prashaant Steel & Alloys is a well-known Grade B8 Bolts maker and retailer. We manufacture ASTM A193 Grade B8 Bolts with the best quality raw materials from our vast inventory. Prashaant Steel & Alloys produces Grade B8 Bolts of excellent quality and has carved out a niche for itself in the industry. Our Grade B8 Bolts are highly common and are used in a number of industries due to their high strength and reliability. Prashaant Steel & Alloys has a well-equipped production facility that can fill huge orders of ASTM A193 Grade B8 Bolts in a range of sizes and diameters. We manufacture Grade B8 Bolts and export them to all of the world’s big cities. We store our goods in suitable wooden boxes and ship them with all appropriate paperwork to prevent product degradation during shipping.

The different classes of these fasteners such as the A193 B8 Washer have different heat treatments applied to them. The B8 is of a higher class and it is made up of AISI 209 steel with nitrogen strengthened. The A193 B8 Material is also called the Nitronic 50 grade. The different types are used for different application purposes. There are classes 1 and 2 in the ASTM A193 B8 Threaded Rod material as well. The class 1 has 75ksi minimum tensile strength and 30ksi minimum yield strength where the class 2 has 125ksi minimum tensile strength and 100ksi minimum yield strength. The ASTM A193 B8 Studs are used with pipes mostly where the stud is inserted into the hole for welding of the fasteners. The most commonly used fastener of this grade is the Hex Bolt A193 B8. Due to the high tensile strength values, the fasteners can be used under high pressure, high tensile and in high stress applications. As a leading supplier, we produce the a193 b8 Hex bolts and others in all dimensions ranging from ¼ inches to 4 inches and above depending on the type of the fastener. 

ASTM A193 B8 Socket Head Cap Screws are made under the specification covering alloy steel and stainless steel bolts for valves, flanges, pressure vessels and fittings for high pressure services. These fasteners can also be used for special purpose applications. There are screws, bars, bolts, studs, wire and stud bolts in this material grade.
