What is Incoloy 800 fasteners ?

Incoloy 800 is a nickel, chromium and iron alloy that exhibits high resistance to carburization and oxidation in elevated temperature conditions. The Incoloy 800 fasteners can maintain their austenitic structure and they can remain stable after prolonged exposure. They show good resistance in aqueous, oxidizing and reducing environments. The Incoloy 800 countersunk screw shows good performance in temperatures up to 1100 °F.

The nickel content in the Incoloy 800 countersunk screw shows good resistance to precipitation embrittlement and stress corrosion cracking. They show excellent stress rupture creep properties at elevated temperature conditions. Machining the 800 Incoloy socket head cap screw material grade tends to work harden by hot and cold forming. They can achieve higher ductility and formability. The size of the Nickel 800 flat washers ranges between M1-M64.

India's most cost-effective manufacturer of alloy 800 bolts and nuts according to ASTM B564, read about distinction between Inconel 600 and Incoloy 800

What is the distinction between Inconel 600 and Incoloy 800 bolts?
  • Incoloy 600 shows good resistance to corrosion oxidation and high temperature environments.Incoloy 800 bolts are ideal for sulphur containing solutions.
  • Incoloy 800 offers better corrosion resistance than 600 material.
  • Incoloy Alloy 800 stud bolts have higher mechanical properties.
  • Incoloy 600 is preferred for higher temperature environments like nuclear engineering whereas 800 is for aggressive conditions like power generation.
  • Incoloy 600 may require pre heating and post weld heat treatment for preventing sensitization.

What is the maximum operating temperature of Incoloy 800 hex bolts?

TheIncoloy 800 hex bolts have a maximum operating temperature of 1100 °F. The 800H and 800HT materials can be used for temperatures above 1500 °F where creep and stress rupture properties are required. 800HT is resistant to embrittlement even after prolonged exposure to temperatures between 100-1600 °F.

What distinguishes Incoloy 800 from Incoloy 800H?
  • Incoloy 800H is the higher carbon version ofAlloy 800 nuts material.
  • 800H can withstand higher temperatures, It is suitable for applications where prolonged exposure to the elevated temp is required without losing mechanical properties.
  • Incoloy 8800 stud is used for applications where corrosion resistance moderate high-temperature strength is required. 800HT is designed for elevated temperatures with enhanced creep resistance and strength.
  • 800H requires careful considerations for welding to prevent sensitization and intergranular corrosion.
top 5 point where Incoloy 800 differ from Incoloy 825?
  • ASTM B564 UNS N08800 screws material has titanium and aluminium as added content whereas 825 has added molybdenum and copper.
  • DIN 1.4876 washers offer resistance to oxidation and carburization in high temperature environments whereas Incoloy 825 is suitable for aggressive chemical environments.
  • Incoloy 800 has a higher maximum operating temperature than 825.
  • Incoloy 825 has higher mechanical properties.
  • ASME SB564 Werkstoff 1.4876 dowel pins are used in high temperature furnaces, heat exchangers, etc. whereas 825 Incoloy is preferred for corrosive environments like oil 7 gas, marine components, etc.
What is the maximum hardness and working pressure of Inconel 800 threaded rod ?

The hardness of theInconel 800 threaded rod generally ranges between 150 to 240 HB, but the exact measurements depend on the tempering process and specific alloy grade. The working pressure also depends on the diameter, material properties and design specifications of the rod. However, it normally ranges between 3000-10000 PSI.
