As a reputable manufacture and distributor of fasteners in Dubai, UAE, Majid Fasteners deals with high quality industrial fasteners and one of the products is the ASTM A193 B8T bolts. Our bolts have been known as precision, strong, and corrosion resistant and meet international requirements; hence, giving them a high degree of reliability when used in high pressure and high temperature environments. Oil and gas, petrochemical, building, and power industries are some of the sectors that we serve with long lasting high quality fasteners that are customized to meet the requirements of critical projects. Majid Fasteners believes in its mission of excellence, delivery on time, and customer satisfaction, and is your reliable vendor of all fastening needs.
ASTM A193 B8T Bolts are used in high-temperature and corrosive applications. The chemical composition of these materials consists of chrome (either 17% – 20% Cr), nickel (7% – 12% Ni), carbon (max of 0.08% C), manganese (max of 2% Mn), phosphorus (max of 0.045% P) and sulfur (max of 0.03% S). Due to this combination of metals, B8T bolts have very good corrosion resistance and strength. The mechanical properties of B8T bolts include solution annealing providing a minimum of 75 ksi (515 MPa) for tensile strength and 30 ksi (205 MPa) for yield strength. In addition, B8T bolts provide good toughness, are resistant to fatigue and are highly durable under high pressure, temperature and corrosive conditions. As a result B8T bolts are ideal for use in what are often called ‘difficult’ environments, including chemical, petrochemical, oil & gas and marine applications.

Industry sectors that demand high temperature and corrosion resistant fasteners, such as chemical manufacturing plants, petrochemical plants, oil and gas refining, and power generation facilities, rely heavily upon the use of ASTM A193 B8T bolts. These types of bolts can be used to secure components like flanges, valves, pressure vessels and pipelines that operate in highly corrosive or high temperature settings. B8T bolts are also utilized extensively in marine applications, steam and gas turbine applications and structural applications where oxidation resistance is necessary to achieve high strength and reliability. The combination of toughness, reliable operation and durability, makes these bolts ideal for critical joints and high performance industrial applications.
