347 Stainless Steel Pipe - Technical Overview & Specifications

347 is a stable austenitic chromium steel, containing niobium, which can eliminate carbide precipitation, thereby eliminating corrosion during the year. 347 is stabilized by the addition of chromium and tantalum, and provides higher creep and stress rupture properties than alloys 304 and 304L, which can also be used for sensitization and exposure to corrosion problems during the year. The addition of niobium also makes the 347 alloy have excellent corrosion resistance, even better than the 321 alloy.
