Mira Fasteners, a top-notch manufacturer and supplier located in Kuala Lumpur, Malaysia, specializes in high-quality Stainless Steel 347H Bolts designed for tough, high-temperature, and corrosive industrial settings. These bolts are crafted from a stabilized austenitic stainless steel grade that includes niobium (columbium), boosting their resistance to intergranular corrosion after welding. With a higher carbon content, 347H enhances high-temperature strength, making them perfect for heat-intensive applications. Renowned for their outstanding mechanical performance and oxidation resistance, Mira Fasteners’ 347H bolts are a go-to choice in demanding sectors like petrochemical, thermal processing, refineries, and power generation throughout Malaysia and Southeast Asia.
Stainless Steel 347H Bolts are made up of Chromium (17–19%), Nickel (9–13%), Carbon (0.04–0.10%), and Niobium (at least 10 times the carbon content). This unique blend offers remarkable resistance to crevice corrosion, oxidation, and carbide precipitation during welding. These bolts boast a tensile strength of ≥515 MPa, yield strength of ≥205 MPa, and impressive creep resistance at high temperatures. The niobium stabilization effectively prevents intergranular corrosion, making 347H bolts perfect for high-stress, high-heat environments. Their mechanical properties stay reliable in both cryogenic and elevated temperature conditions.
