Emilio Stainless, a reputable manufacturer and supplier located in Manila, Philippines, specializes in high-quality Stainless Steel 348 Bolts that are engineered for outstanding performance in both high-temperature and corrosive settings. Crafted from niobium-stabilized austenitic stainless steel, these bolts boast remarkable resistance to intergranular corrosion and oxidation. SS 348 is known for its excellent weldability, strength, and toughness, even after prolonged exposure to elevated temperatures. Emilio Stainless guarantees that each bolt adheres to rigorous quality standards and international specifications, making them a go-to choice for industries like petrochemical, power generation, pharmaceuticals, and heat treatment, where dependable fastening solutions are crucial.
Stainless Steel 348 Bolts are made up of 17–19% chromium, 9–13% nickel, and niobium (columbium) for stabilization, along with trace amounts of manganese, silicon, and carbon (≤0.08%). This specific composition boosts the alloy’s resistance to carbide precipitation during welding and high-temperature applications. The bolts deliver a tensile strength of about 515 MPa and a yield strength close to 205 MPa, along with impressive ductility and toughness. They maintain excellent mechanical stability under thermal stress and can resist oxidation up to 900°C, making them perfect for continuous use in challenging heat and corrosion-heavy environments.
