Brian Fasteners is a trusted manufacturer and supplier located in Houston, USA, specializing in a top-notch selection of Stainless Steel 347 Stud Bolts. Known for our commitment to quality craftsmanship and dependable service, we proudly serve clients from a variety of industries by providing fasteners that are built for high performance and durability. Our Stainless Steel 347 Stud Bolts are specifically designed to excel in high-temperature and corrosive settings. With rigorous quality control and adherence to international standards, Brian Fasteners guarantees that every product meets the demanding requirements of sectors like oil & gas, power generation, chemical processing, and marine engineering.
These Stainless Steel 347 Stud Bolts are primarily made up of iron, chromium (17–19%), nickel (9–13%), and a maximum of 0.08% carbon, with stabilization from columbium and tantalum. This unique chemical makeup boosts the alloy’s resistance to intergranular corrosion, particularly after being subjected to high temperatures. On the mechanical side, 347 boasts a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of around 40%. These bolts retain impressive mechanical properties even at elevated temperatures, including resistance to creep and stress rupture, making them perfect for high-stress and heat-intensive industrial applications.

Stainless Steel 347 Stud Bolts are commonly utilized in situations that demand outstanding strength and corrosion resistance at high temperatures. They are essential in heat exchangers, reactors, furnace components, boilers, and exhaust systems found in petrochemical and power generation facilities. The stabilized nature of the 347 alloy prevents carbide precipitation during welding and heat exposure, ensuring the structural integrity of the bolts. Consequently, industries such as aerospace, oil & gas, marine, and chemical processing prefer these bolts for their durability, especially in continuous service conditions that involve aggressive media and fluctuating thermal cycles.
We carefully assemble our stainless steel 347 stud bolts at Brian Fasteners to ensure they arrive in perfect condition. Our packaging uses durable materials and safe processes to protect the bolts from damage during transportation and handling.
