Mira Fasteners, a well-respected manufacturer and supplier based in Kuala Lumpur, Malaysia, specializes in top-quality Stainless Steel 347H Nuts that are perfect for high-temperature and corrosive settings. Crafted from niobium-stabilized austenitic stainless steel, these nuts boast exceptional resistance to intergranular corrosion, even after welding and exposure to high heat. With improved mechanical strength, oxidation resistance, and thermal stability, 347H nuts are the go-to choice for demanding environments like petrochemical processing, power generation, thermal plants, and refineries. Mira Fasteners guarantees precise dimensions, adherence to global standards, and consistent quality, providing fasteners that meet the tough requirements of industries throughout Malaysia and Southeast Asia.
Stainless Steel 347H Nuts are made up of Chromium (17–19%), Nickel (9–13%), Carbon (0.04–0.10%), and are stabilized with Niobium (columbium) to avoid carbide precipitation during welding. These nuts deliver a tensile strength of ≥515 MPa and a yield strength of ≥205 MPa, along with impressive creep resistance at high temperatures. Thanks to their niobium content, they offer outstanding intergranular corrosion resistance, making them ideal for continuous use in high-heat environments. 347H nuts retain their strength and integrity even under mechanical and thermal stress, ensuring reliable fastening solutions in challenging industrial conditions.
