Buy B8 Hex Nuts and ASTM A193 Grade b8 Hex Screw at low price in India.
The ASTM A193 Grade B8 Bolts are used in high temperature and high corrosion environments such as chemical processing plants and in power generation plants. The ASTM A193 B8 Class 2 Bolts are used in heat exchangers as well. They could be used in high corrosive environments such as marine industries, dyeing industries and mining industries. The ASTM A193 B8 Nuts are stronger and harder and do not wear off quickly. The grade B8 has two classes. class 2 is stronger than class 1. The class 2 has higher HBW at 321 max and lower HRC at 35 max. These properties allow these two classes to be used uniquely with unique applications. The ASTM A193 B8 Studs can be used along with ASTM A193 B8 Threaded Rod in high heat applications because they are heated and water quenched to provide maximum corrosion resistance and strength. Our B8 Hex Nut is used with tight connections where strength is more important. All our products are of high quality and we test them prior to shipping. You can submit your inquiries and we will be in contact with all the details you want.
