There are different types of heat treatments such as the carbide solution treatment. This is also known as the solution annealing of the ASTM A193 B8 Class 2 Stainless Steel Nuts. It provides the products with maximum strength and hardness. The two classes of the fasteners range in size and in strength values. The class 1 ASTM A193 B8 Cl2 Nut Bolts with diameters less than ¾ inches have 125ksi minimum tensile strength and 100ksi minimum yield strength. The ones up to 1 inches have 115ksi tensile strength and 80ksi yield strength. The ASTM A193 Grade B8 Class 2 Bolts that are lower than ¼ inches have 105ksi minimum tensile strength and 65ksi minimum yield strength whereas the tensile strength is 100ksi and yield strength is 50ksi for the SA193 B8 Cl2 Bolts that are up to 1 ½ inches. There are also different types of fasteners such as bolts, nuts, studs, screws and washers. The SA193 B8 Class 2 Stud Bolts are used in special cases where the fasteners have to be welded. These are some of the high tensile fasteners so that A193-B8 Cl.2 Bolts are used in high tensile applications. The Brinell hardness of the class 1 A193 B8 Socket Head Cap Screw and other fasteners is at 223HBW max where the class 2 fasteners have 321HBW max. As a leading supplier, we produce and supply all different types of fasteners such as the ASTM A193 B8 Threaded Rod.
