What is ASTM A193 B8 Bolts?
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.
