Stainless Steel 347H Bolts consist of a majority of iron, nickel (9–13%), chromium (17–19%), and columbium (niobium), which improves resistance to intergranular corrosion at high temperatures. The high carbon composition of 347H offers enhanced creep strength, tensile strength, and long-term resistance in conditions up to 900°C. These bolts show very good resistance to acidic and chloride-rich conditions and deliver oxidation resistance and low maintenance needs. Their strength, corrosion resistance, and thermal stability make them very dependable fasteners for vital applications with superior mechanical properties under severe operating conditions.
Stainless Steel 347H Bolts find extensive application in industries where they must perform consistently well under corrosive and high-temperature environments. In chemical plants, the bolts are used to hold equipment open to corrosive and acidic, as well as oxidizing, atmospheres. In aerospace applications, they offer safe fastening of components exposed to extreme heat and stress. They are also used in oil and gas plants, providing sulfide stress cracking resistance, and in nuclear reactors, where there is a need for high-temperature and radiation resistance. Their long service life, stability, and strength ensure that they are key fastening products used in power plants, refineries, and other hazardous industrial applications where regular bolts do not meet the demands.
