Product Description

 Good strength Alloy 718 (UNS N07718) 16 inch Seamless Steel Pipe 6-12m Nickel alloy pipe

 

Product Description

 

Key Features:

  • Good strength/ductility properties from sub-zero temperatures to over 750°C
  • Acceptable corrosion resistance and fatigue resistance in a wide variety of corrosive chemicals such as seawater and industrial acids
  • Non-magnetic and spark resistant
  • Excellent resistance to stress corrosion cracking, chloride stress corrosion & sulphide stress cracking
  • High fatigue strength in seawater

 

Applications:

  • Oil & Gas industry wellhead components, gate valves, choke stems, fasteners, packers, clamps, tubing hangers, downhole equipment
  • Power generation applications such as fasteners, turbines
  • Aerospace components
  • Nuclear power plant containment vessels, valves
  • Engineering applications between 750°C and cryogenic temperatures

Description:

Alloy 718 is a high-strength, corrosion-resistant nickel chromium alloy supplied in the hot worked, solution annealed and age hardened condition. The addition of Nb, Ti, Al and Ni form a series of precipitates during the controlled solution annealing and ageing process steps, resulting in a significant increase in strength and hardness compared with alternative nickel alloys. These tensile and creep rupture properties are maintained from cryogenic to elevated temperatures, making it suitable for applications between -250oC – 750oC.

Chemical Composition:

  Cr Ni Mo Co Nb (+Ta) Ti V W Cu C Mn N Si P S Fe Al

Max                 34.00 0.30 2.00   0.50   0.024 2.50  

Notes:

  1. Testing shall be carried out in accordance with ASTM A370 (tensile), ASTM E18 (hardness)
  2. Minimum properties quoted (tested at room temperature in a longitudinal direction)
  3. Testing performed on each melt of material per heat treatment batch
