We offer These ASTM A193 B8T Bolts as per DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: B8T bolts are made from Grade 347 stainless steel, which provides excellent resistance to corrosion, especially in environments where exposure to moisture or chemicals is a concern. This makes them suitable for applications in marine environments, chemical processing plants, and similar settings.
High Temperature Stability: Grade 347 stainless steel has good high-temperature properties, including resistance to intergranular corrosion and oxidation at elevated temperatures. This makes ASTM A193 B8T bolts suitable for use in applications where they will be exposed to heat or thermal cycling.
Strength and Durability: These bolts are designed to provide high tensile strength and durability, meeting specific mechanical requirements outlined in ASTM A193 standards. They are capable of withstanding high loads and stresses, making them reliable for structural and mechanical applications.
Compliance with Standards: ASTM A193 B8T bolts are manufactured according to ASTM A193 standards, ensuring they meet stringent criteria for quality, performance, and safety. This compliance provides assurance of their reliability in critical applications.
Versatility: They are suitable for a wide range of applications in industries such as construction, petrochemical, power generation, and transportation where corrosion resistance and mechanical strength are essential requirements.
ASTM A193 B8T 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.
ASTM A193 B6 Bolts, being stainless steel with a high chromium content, exhibit good resistance to galvanic corrosion when paired with compatible materials. However, caution should be exercised when in contact with dissimilar metals to avoid potential galvanic corrosion issues due to differing electrochemical potentials.
