Alloy 347 is a stable, austenitic, chromium steel containing an alloy that eliminates carbide precipitation and, therefore, intergranular corrosion. alloy 347 is stabilized by the addition of chromium and tantalum, providing higher creep and persistence performance than alloys 304 and 304L, which can also be used for sensitization and exposures where intergranular corrosion is a concern. In addition, the addition of niobium gives alloy 347 excellent corrosion resistance, even better than alloy 321. 347H is the higher carbon composition form of alloy 347, with improved high temperature and creep properties.
