347. UNS. S34700. Description. 1.4550 / AISI 347 is an austenitic chromium-nickel stainless steel with titanium and niobium addition. Special properties. Good resistance to intergranular corrosion. ASTM A312 TP347 Seamless Stainless Steel Pipe, ASME ASTM A312 Gr Tp347 is an austenitic stainless steel stabilized with columbium. The addition of columbium makes it perform under high oxidation condition under high temperatures at around 800 degrees Celsius. The A312 Tp347 is stronger and durable. There are different sizes of the pipes in the SA 312 Tp 347 grade that range from 1/2inches to 24
Grades Austenitic Stainless Steel. Steels with Chromium content between 16% and 26%, Nickel between 7% and 35% and Carbon (max. 0.15%), cannot be strengthened by quench hardening, but only through cold working (e.g. cold drawing). The main features of these steels are their resistance to corrosion, which is generally higher than other stainless Austenitic steels - BÖHLER Edelstahl GmbH & Co KGAustenitic steels; Duplex and super duplex stainless steels; Plastic mould steels; Heat treatable steels and precipitation hardening steels; X6CrNiNb18-105 - - Standards - - A760 - Material Numbers:1.4550 X6CrNiNb18-10 S34700 - GB 18457-2001, PDF in English. - Chinese StandardTubing shall be made from austenitic stainless steels, such as X2CrNi18-9, X5CrNi18-9, X6CrNiNb18-10, X5CrNiMo17-12-2, X6CrNiMoTi17-12-2, X6CrNiMoNb17-12-2 in accordance with ISO/TR 15510:1997, or made from other austenitic stainless steels equivalent to the above stainless steels.

Chandan Steel Limited has the privilege of being an ISO 90012008, AD 2000 Merkblatt, Pressure Equipment Directive PED 97/23/EC approved and certified Corporate House. Equipped with modern machines and technical support of global nature, ensuring SS347 - Ferrous & Nonferrous Alloy for PipingSimilar to SS321, stainless steel 347(SS347) is an austenitic stainless steel with deliberate addition of tantalum(Ta) and niobium(Nb) to the basic stainless steel 304(SS304).The Nb+Ta addition reduces the sensitization of carbide precipitation during welding process which also improves its resistance to intergranular corrosion.
