Grade 347 is an austenitic stainless steel that is stabilized with niobium to enhance its resistance to intergranular corrosion. This stabilization makes it particularly effective in high-temperature environments (Excellent resistance to creep and stress rupture at elevated temperatures), where it exhibits excellent mechanical properties and corrosion resistance (Intergranular Corrosion Resistance, General Corrosion Resistance). Grade 347 is widely used in applications requiring high temperature and corrosion resistance, such as in the aerospace, chemical, and power generation industries.
