We offer These ASTM A193 B8 CL3 Stud Bolts as per DIN, ISO, JIS or ANSI Standard.
High Temperature Resistance: These bolts are made from AISI 304 stainless steel, which offers excellent resistance to high temperatures up to 1000°F (537°C) without losing mechanical properties. This makes them suitable for applications where elevated temperatures are a concern.
Corrosion Resistance: AISI 304 stainless steel provides good resistance to corrosion in a wide range of environments, including those with acidic and chloride-containing atmospheres. This corrosion resistance ensures longevity and reliability in harsh conditions.
Mechanical Properties: ASTM A193 B8 CL3 bolts are heat-treated to achieve specific mechanical properties, including tensile strength and hardness, which are essential for ensuring the structural integrity and reliability of the bolted joint under operational loads.
Suitability for Various Applications: These stud bolts are widely used in industries such as chemical processing, petroleum refining, power generation, and food processing where their corrosion resistance and high-temperature capabilities are crucial.
Compliance with Standards: ASTM A193 B8 CL3 studs bolts are manufactured to meet ASTM A193 standards, ensuring consistency and reliability in performance. They also typically comply with other relevant standards and specifications required by the industry.
ASTM A193 B8 CL3 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.
