Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Incoloy 800 Bolts And Nuts, which is extremely resistant to corrosion and even in acidic environment. Because of its high nickel and chromium content, Incoloy 800 Hex Head Bolts resist oxidation and carburization at high temperatures. The chemical balance allows the Incoloy 800H Square Nuts to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. For the first time, aluminum and titanium were listed as purposeful additions, and annealed Incoloy 800HT U-Bolts was differentiated from solution – annealed material.

Incoloy 800 Lock Nuts will not become embrittled even after long periods of usage in the 1200 Degree F – 1600 Degree F range where many stainless steels become brittle. The restricted chemical compositions, combined with the high temperature anneal, assure these materials have greater creep and rupture strength when compared to Incoloy 800H Eye Bolts.

Many companies in a wide range of industries utilize Incoloy 800HT Wing Nuts for a number of applications, especially those that deal with temperatures about 1100 Degree F (600 Degree C). Incoloy 800 T-Bolts is especially useful for high – temperature equipment in the petrochemical industry since the alloy doesn’t form the embrittling sigma phase after long time exposure at 1200 Degree F. Incoloy 800H Panel Bolts have nickel – chromium – iron as the base metals, with additives such as molybdenum, copper, silicon and nitrogen.
