Harshita Stainless, a well-respected manufacturer and supplier located in Delhi, India, specializes in top-notch Stainless Steel 348 Fasteners tailored for industrial and engineering needs that require outstanding thermal and corrosion resistance. These fasteners are crafted for high-performance settings, particularly where intergranular corrosion resistance and high-temperature strength are vital. Using only the finest raw materials and precise manufacturing techniques, Harshita Stainless guarantees that each SS 348 fastener complies with both national and international standards. With a strong emphasis on quality, customization, and prompt delivery, the company serves various sectors, including chemical processing, power generation, aerospace, and oil & gas, catering to clients both locally and globally.
Stainless Steel 348 fasteners are crafted from a stabilized austenitic stainless steel alloy that contains 17–20% chromium, 9–13% nickel, and columbium (niobium) to prevent carbide precipitation during welding. This composition significantly boosts their resistance to intergranular corrosion. They boast a tensile strength of about 515 MPa, a yield strength of 205 MPa, and a Brinell hardness ranging from approximately 150 to 200 HB. SS 348 fasteners maintain their mechanical strength even at elevated temperatures and exhibit excellent resistance to stress rupture and creep. In their annealed state, they are non-magnetic, making them ideal for applications that demand stability, durability, and resistance to scaling and thermal fatigue.
