Sachiya Steel International offers a wide quality range of Incoloy 800 Threaded Forged Fittings, where our products are used for fitting purpose in number of applications. Incoloy 800 Forged Threaded Elbow (UNS N08800) is extremely resistant to corrosion, even in acidic environment. Incoloy 800H Forged Threaded Tee (UNS N08810) is excellent resistance to oxidation, sulfidation, and carburization. Heat treatment retorts, muffles jigs and fixtures have also used these Incoloy 800HT Forged Threaded Cross (UNS N08811) to a great effect.
Our Alloy 800 Forged Threaded Fittings are resistant to embrittlement from precipitation of sigma phase and chloride stress – corrosion cracking due to the nickel content. The higher strength in this Alloy 800H Forged Threaded Coupling results from close control of carbon, aluminum and titanium contents in conjunction by means of a high temp anneal. Meanwhile, our Alloy 800HT Forged Threaded Union are also being offered in different sizes and shapes to our customers.

Whether for hot working or cold working, these Incoloy 800 Forged Threaded Bushing offer workability similar to austenitic stainless steels. Our Incoloy 800H Forged Threaded Plug is commonly welded using bare wire for a number of applications under 1450 Degree F. These Incoloy 800 Forged Threaded Hex Plus was the first of these alloys and it was slightly modified into Incoloy 800H Forged Threaded Hexagonal Plus.
