With years of experience and cutting-edge manufacturing skills, we provide a diverse selection of SS 348 fasteners, including bolts, nuts, screws, washers, and even custom solutions tailored to your needs. Our SS 348 fasteners are renowned for their outstanding resistance to high temperatures and intergranular corrosion, meeting international quality standards like ASTM and DIN. We proudly serve various industries, including aerospace, petrochemical, pharmaceutical, and food processing. At Aditya Stainless, we’re dedicated to delivering durable, precision-engineered Stainless Steel 348 Fasteners for a wide range of industrial applications across India.
Stainless Steel 348 Fasteners are crafted from a stabilized austenitic stainless steel alloy that contains 17-19% Chromium, 9-13% Nickel, and Columbium (Niobium) for stabilization, along with trace amounts of Manganese, Silicon, and Phosphorus. They boast excellent resistance to intergranular corrosion, particularly after being exposed to high temperatures. Their mechanical properties include a minimum tensile strength of 515 MPa, a yield strength of at least 205 MPa, an elongation of 40%, and a maximum Brinell hardness of 201. SS 348 fasteners can withstand temperatures up to 870°C, making them perfect for high-stress and high-temperature applications.
