Supplier of ASME SA193 Grade B8 Hex Bolts, check Difference Between grade b8 vs b8m here
astm a193 grade b8 bolts are high tensile steel bolts that are used in construction, chemical and petroleum industrial applications. Viha Steel & Forging is a leading manufacturer and supplier of the different types such as the astm a193 b8 stud bolts and others. There are class 1 and class 2 fasteners in this grade. The class 1 fasteners are standard whereas the class 2 fasteners are hardened. The class 2 is used where extra strength and hardness are needed. The ASME SA193 Grade B8 Hex Bolts can be used in medium and high temperature applications.
The material is good for cryogenic applications as well. The applications include waste water processing and construction as well. There are different types of fasteners and the B8 Screws are special. The screws are used in application conditions where there is no space for nuts and the fastener has to drive fully into the material surface. Sometimes, the application surface of two components has to be fitted together. The astm a193 b8 threaded rod is used in such conditions. The material class 1 has 75ksi minimum tensile strength and class 2 has minimum 105MPa tensile strength. The minimum yield strength ranges from 30ksi to 100ksi. The sa 193 gr b8 chemical composition has carbon, manganese, sulfur, phosphorus, chromium, nickel and molybdenum.
The composition provides the material with high strength and hardness. The class 1 has 223HBW max and the class 2 has 321HBW max. There are also other types of fasteners such as the A193 B8 Washer which is used with bolts and nuts to tighten the components better. Please feel free to contact us for more information on the different types and prices of the B8 fasteners.
