Harshita Stainless, a well-respected name in the stainless steel sector located in Delhi, India, stands out as a top manufacturer and supplier of Stainless Steel 347H Fasteners. They’re renowned for providing high-quality products that can withstand extreme temperatures and pressures. Crafted with precision and adhering to global standards, these fasteners boast impressive mechanical strength and resistance to intergranular corrosion. Harshita Stainless offers a diverse selection of 347H fasteners in various sizes and specifications, serving industries like petrochemical, power generation, and chemical processing, where reliable, heat-resistant fastening solutions are crucial for long-term success.
Stainless Steel 347H is a high-carbon, niobium-stabilized austenitic stainless steel alloy that contains 17–20% chromium, 9–13% nickel, and 0.04–0.10% carbon, along with columbium (niobium) for stabilization. This alloy provides enhanced creep strength and resistance to sensitization at high temperatures. SS 347H fasteners have a tensile strength ranging from 550 to 750 MPa, a yield strength of about 240 MPa, an elongation of 35–45%, and a hardness between 80 and 90 HRB. These characteristics make them perfect for high-temperature applications and situations involving repeated thermal cycling and mechanical stress.
