Brian Fasteners is a Houston, USA-based prominent manufacturer and supplier of top-notch ASTM A193 B6 Stud Bolts. With years of experience and dedication to quality, Brian Fasteners is a specialist in providing trusted fastening solutions to various sectors such as oil & gas, petrochemical, and power generation. Our ASTM A193 B6 Stud Bolts are designed to perform in extreme high-temperature and high-pressure applications with superior performance. Supported by a team of experts, state-of-the-art manufacturing facilities, and timely delivery services, we have emerged as a reliable partner for clients looking for durability and accuracy in fasteners.
ASTM A193 B6 Stud Bolts are made from AISI Type 410 stainless steel with martensitic structure and high mechanical properties. The standard chemical composition consists of 11.5–13.5% Chromium with little Carbon content (≤0.15%), which increases corrosion resistance and hardness. The bolts have high tensile strength (at least 760 MPa), yield strength (at least 480 MPa), and good hardness (maximum Brinell 223). They also have good scaling resistance and oxidation at high temperatures. Heat treatment additionally increases their mechanical performance to suit high-stress and corrosive conditions.

ASTM A193 B6 Stud Bolts are commonly employed in high-pressure and high-temperature applications in many industries. Their high strength and resistance to corrosion make them perfect for pressure vessel bolting, valves, flanges, and fittings in power plants, oil refineries, and chemical process facilities. They can also be used in marine settings and structural applications where tough fastening solutions are demanded. Due to their resistance to thermal cycling and severe chemical exposure, B6 Stud Bolts are a choice of preference for critical pipeline and heat exchanger joints that guarantee secure and reliable connections under rigorous operating conditions.
We maintain strict quality control by performing various tests such as Hardness, Spectro Analysis, PMI Testing, Flattening, Micro and Macro Tests, Pitting Resistance, Flaring, and IGC Tests. We provide detailed documentation, including commercial invoices, packing lists, Certificates of Origin, and Guarantee Letters. To ensure complete client satisfaction, we also offer Third-Party Inspection Certificates.
