Why Stainless steel 347?

More Detail on ss 347/347H

ss 347 & 347H is known as its high alloy steel . ss 347 is known for its good and high corrosive resistance than any other austenitic stainless steel. Stainless steel 347 is rich in chromium , it contain atleast 10% Chromium . The average range of chromium in stainless steel 347 & 347H is 4 to 30%. ss 347 & 347H is combination of austenitic steel and martensitic steel which is known as precipitation hardened steel. ss 347 & 347H can be easily hardened by cold working and ss 347 & 347H is non magnetic in annealed condition . UNS number for ss 347 is UNS S34700 and for 347H is UNS S34709. SS 347 & SS 347H is in common austenitic stainless steel family such as ss 316, ss 304, ss 321. ss 347 and 347H is similar to 321 but it is more corrosion resistance in oxidizing Environment. More amount or columbium and tantalum in ss 347 help it good forming and welding . ss 347 & 347H is mostly used in high temperature application, welding and fabrication application and even power generation application. Ss 347 welding wire are AWS ER47.

Key Properties of SS 347/347H Flange

ss 347 Flanges & ss 347H Flange

  • ss 347 and 347H Can be easily welded and processed by common standard Method. AWS E/ER347 filler wire can be used .
  • ss 347 & 347H can me exposed to maximum temperature of scaling to 2100-2300 °F and are suggested for Bending, Forging, upsetting and other hot process .
  • ss 347 & 347H can not be suitable for work below 1700°F
  • ss 347 should be anneled and water quenched after maximum corrosion resistance
  • ss 347 is Ductile and easily forms
  • ss 347 is welded by common standard process and post weld heat treatment is not required.
  • SS 347 hardening is similar to ss 321

Other Properties OF ASTM A182 F347

ss 347 flanges & ss 347H Flange

  • Cold Working– 347 & 347H are very ductile and can be easily cold world by deep drawing, Forging, upsetting, bending etc . It may require immediate annealing. High Hardness and strength is achieved should cold working
  • Formability – 347 & 347H is highly formability due to its combination of lower strength and shapes
  • Weldability – Stainless steel is considered as weldable by common fusion and resistance technique both with and without filler metals.
  • Corrosion Resistance – SS 347 & 347H is compared with ss 304 grade in annealed condition. General resistance of ss 347 is affected if heated for long period of time .It has been developed for applications. Where the unstabilized Chromium-nickel steel,such as stainless steel 304 would be susceptible to intergranular corrosion.
  • Heat Theatment – SS 347 is heat to 950-1120°C and rapidly cooled for maximum corrosion resistance. Ss 347 can not be hardened by heat treatment
