Specification of ASTM A193 B8 Bolts?
The ASTM A193 B8 bolts cover standard specifications for 304/304L bolting material. These bolts are used for materials having high tensile properties that can suffice in higher temperature and pressure service. The bolts are divided into 3 classes namely Class 1, Class 2, and Class 2B. The bolts are designed with a chemical composition of carbon, manganese, phosphorous, sulfur, silicon, chromium, nickel, and other constituents. They showcase good mechanical properties and are available possessing different sizes and shapes.
What material is a B8 stud?
The B8 stud is designed with the AISI 304 stainless steel. This fastener has threaded ends on both its ends, with the unthreaded end in its center. These studs have an austenitic structure and can be treated using carbide solution treatment procedures.
What are the applications of ASTM A193 B8 Stainless Steel Bolts and Nuts?
The ASTM A193 B8 is a standard specification of austenitic corrosion resistant steel fasteners. These bolts and nuts are used in tandem to securely seal different equipment in the system. The fasteners are common in petrochemicals, heat exchangers, power generation, pharmaceutical equipment, pharmaceuticals, and seawater equipment. They are also seen in off-shore drilling companies, specialty chemicals, aircraft manifolds, etc.
Cost Difference Of ASME SA 193 B8 Fasteners In India And Singapore
The price of the ASME SA 193 B8 fasteners is dependent based on the type of fasteners and sizes. The price of the ASME SA 193 B8 Fasteners in India ranges from $0.971 to $1.44 per kg. Similarly, the price of the ASME SA 193 B8 Fasteners in Singapore range from $1.34 to $2.23 per kg.
