We offer These ASTM A193 B8T Stud Bolts as per DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: ASTM A193 B8T stud bolts are made from grade 347 stainless steel, which contains titanium and niobium. These elements enhance its resistance to intergranular corrosion, making it suitable for environments where exposure to corrosive substances is a concern.
High Temperature Strength: Grade 347 stainless steel, from which ASTM A193 B8T stud bolts are made, exhibits good strength retention at elevated temperatures. This makes it suitable for applications where high temperatures are encountered, such as in industrial furnaces or exhaust systems.
Weldability: ASTM A193 B8T material is readily weldable using common welding techniques, which allows for flexibility in construction and repair applications without compromising the integrity of the bolt.
Durability: The combination of corrosion resistance and high temperature strength ensures that ASTM A193 B8T stud bolts have a long service life, even in demanding environments.
Versatility: These stud bolts are versatile and can be used in a wide range of industries and applications, including chemical processing, oil and gas production, power generation, and more.
ASTM A193 B8T Stud Bolts applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
