Renowned for their precision engineering and strict adherence to international standards, Harshita Stainless provides durable, corrosion-resistant fasteners that consistently perform well in high-temperature and corrosive settings. With cutting-edge production capabilities and a strong focus on customer satisfaction, the company offers bolts in a variety of sizes, threads, and finishes to meet diverse requirements. Their Stainless Steel 348 Bolts are perfect for industries that demand strength, heat resistance, and long-lasting durability in tough working conditions.
Stainless Steel 348 is a niobium-stabilized austenitic stainless steel alloy that contains about 17–19% chromium, 9–13% nickel, ≤0.08% carbon, ≤2% manganese, ≤0.75% silicon, along with trace amounts of niobium and tantalum. These elements enhance its resistance to intergranular corrosion, making it suitable for welding and high-temperature applications. In terms of mechanical properties, it boasts a tensile strength of around 620 MPa, yield strength ranging from 240–275 MPa, an elongation of about 45%, and a Rockwell B hardness of 83–85. These characteristics ensure that Stainless Steel 348 Bolts maintain their integrity even under high stress and thermal exposure.
