Application of Stainless Steel 347 / 347H EFW Pipes

Stainless Steel 347 / 347H EFW Pipes

Austenitic chromium stainless steel is the alloy. It contains Cr 17-20%, Ni 9-13%, C 0.04-0.08 percent, MN 0.5-2 percent, S 0.30 percent, and Si 0.75 percent, among other elements. Heavy welded equipment is made of this alloy. Mechanical properties of stainless Steel 347/347h EFW Pipes has tensile Strenght Min 515Mpa and yield Strenght min 205Mpa with longitudinal Of 35%. At low temperatures, the alloy can be used in nitric solutions, most diluted organic acids at moderate temperatures, pure phosphoric acid at lower temperatures, and up to 10% diluted solutions at high temperatures.

The addition of niobium (Nb) as a stabilizing element in 347H EFW, a higher grade than AISI 321H EFW, maximizes intergranular corrosion. The mechanical qualities of SS 347 EFW Pipes are good, and it has great resistance to intergranular corrosion. Stainless Steel 347/ 347H EFW Pipes are made of stabilized stainless steel, which has a high resistance to intergranular corrosion as its main benefit. Heat cannot be used to harden these Stainless Steel 347 / 347H EFW Pipes, however cold working can. Columbium is used as a stabilizing element in SS 347H EFW pipes to maximize its main feature, such as resistance to intergranular corrosion. 347H Stainless Steel Pipes were designed for better strength and creep resistance at temperatures beyond 1000°F (537°C).

Application of Stainless Steel 347 / 347H EFW Pipes

347H stainless steel EFW pipe is primarily utilized in applications where corrosion resistance and long-term operation at temperatures ranging from 800°F to 1500°F (427°C to 816°C) are critical. It’s also a better choice for big welded things that can’t be re-annealed.

In industries such as food processing, wastewater treatment, pharmaceutical, and chemical processing, Ss 347H ERW pipe is frequently utilized. We supply piping to the petroleum refinery, gas processing, aerospace, and other industries.
