Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Incoloy 825 Bolts And Nuts, which is has a high level of corrosion resistance. Cold forming in our Incoloy 825 Hex Head Bolts may be done using standard tooling although lain carbon tool steels are not recommended as they tend to produce galling. These Incoloy 825 Hex Head Nuts resists general corrosion, crevice corrosion, pitting, inter – granular corrosion, and stress – corrosion cracking in both oxidizing and reducing environments. Brittle phases may form in our Incoloy 825 Square Bolts at temperatures above 540 Degree C, so it is not normally used at these temperatures, where creep – rupture properties would be design factors.

These Incoloy 825 Square Nuts is a combination of nickel and chromium alloy that has excellent tensile strength and resistance to oxidation as well as carburization properties. Our Incoloy 825 U-Bolts is resistant to chloride stress – corrosion cracking and pitting, where the molybdenum as well aids resistance to pitting and crevice corrosion. These Incoloy 825 Lock Nuts is often used in chemical process equipment, propeller shafts, spent nuclear fuel element recovery, tank trucks, and so on.

Our Incoloy 825 Eye Bolts is characterized by good resistance to oxidizing and non – oxidizing hot acids. These Incoloy 825 Eye Nuts is the forerunner of many of the Molybdenum containing nickel iron chromium alloys which have seen service over the past century.
