Incoloy 800 material is widely used for manufacturing pipes present in various high strength equipment.They can highly resist carburization and oxidation, which is why Incoloy 800 pipe can be used in petroleum processing plants, pulp & paper industries, etc.The seamless variants of the pipe are usually cold drawn and have high creep resistance properties.Due to the added nickel in the alloy, Incoloy 800 is highly ductile and chromium enhances the corrosion resistance properties.They also have high temperature resistance and hence, are ideal for different heat treating equipment.
The Nickelvac® 800 annealed pipe has high precision and can be used in steam generators, sheathing of electric heating elements, and so on.They can also protect other materials from being exposed to heat due to their high-temperature properties.The pipes are mostly solution annealed and have good rupture resistance.
Inconel 800 pipe is costly compared to standard stainless steel pipes.They are nickel and chromium based superalloys that come with some unique properties, that contribute to their high cost.The exact price of Nicrofer® 3220 pipe in India can vary with the suppliers, their internal costings and market conditions.The prices are also dependent on the size & dimension of the pipe, their manufacturing process, any added customization and the delivery location.The quality and added requirements like different test certificates can add to the pipe cost.

So, whether Incoloy 600 or 800 is a better choice would depend on your application requirements.If your pipe is exposed to sulfur compounds and needs high temperature strength and corrosion resistance, then alloy 600 is preferred.But if you have higher temperature, corrosive substances and mechanical requirements, WNR 1.4876 cold finished pipe is a better choice.
The equivalent of welded pipe Incoloy 800 or UNS N08800 material is UNS N08810 and W.Nr.1.4958.The Incoloy 800H material comes with a higher carbon content in the alloy.Thus, it has enhanced creep resistance and high temperature properties.
The UNS N08800 pipe material is a nickel, chromium and iron alloy with trace amounts of carbon, aluminium and titanium.The high temperature and corrosion resistance properties of the material are achieved through solid solution strengthening.It forms a stable oxide layer at high temperatures which offers protection against further oxidation or corrosion.
