We pride ourselves on delivering top-notch fastening solutions that are specifically designed to thrive in high-temperature and corrosive settings. Stainless Steel 347 is a stabilized austenitic alloy that’s perfect for welding and handling elevated temperatures. Our bolts are crafted using cutting-edge processes to guarantee durability, precise dimensions, and resistance to intergranular corrosion. Trusted by industries like petrochemical, aerospace, and power generation, Bilal Fasteners is committed to providing reliable products at competitive prices, ensuring timely delivery, and offering custom solutions that meet stringent industrial standards and performance needs.
Stainless Steel 347 bolts are primarily made up of iron, chromium (17–20%), and nickel (9–13%), with columbium (niobium) added for stabilization. This unique blend helps prevent carbide precipitation during welding and exposure to high temperatures. The material boasts impressive mechanical properties, featuring a tensile strength of about 515 MPa, a yield strength of roughly 205 MPa, along with good elongation and impact resistance. It maintains its structural integrity even at elevated temperatures and offers excellent resistance to oxidation, intergranular corrosion, and creep deformation—making it a top choice for high-heat applications.
