Punit Fasteners, a well-respected manufacturer and supplier located in Delhi, India, specializes in top-notch ASTM A193 B8C Fasteners designed for high-performance use in challenging environments that involve corrosion and high temperatures. Crafted from Type 347 stainless steel, these fasteners are enhanced with columbium (niobium) to boost their resistance to intergranular corrosion, particularly after welding and extended heat exposure. Our B8C fasteners, which include bolts, nuts, washers, and studs, are produced in strict accordance with ASTM A193 standards, guaranteeing exceptional mechanical strength, precision, and durability. Catering to industries like oil & gas, petrochemical, marine, and power generation, Punit Fasteners is committed to providing dependable fastening solutions with quick service and a global presence.
ASTM A193 B8C Fasteners are made from Type 347 stainless steel, which consists of 17–20% chromium, 9–13% nickel, and columbium (niobium) for stabilization. This unique blend improves the alloy’s resistance to sensitization and intergranular corrosion, even after multiple welding processes or prolonged exposure to high temperatures. These fasteners boast a minimum tensile strength of 515 MPa and a yield strength of 205 MPa, along with impressive elongation, ductility, and creep resistance. B8C fasteners maintain their mechanical integrity and corrosion resistance in tough conditions, making them perfect for pressure-retaining applications in critical and corrosive industrial settings.
