Sachiya Steel International is one of the Leading Manufacturer And Exporter Of High Quality Incoloy Alloy 925 Bolts And Nuts, which is used in various applications requiring a combination of high strength and corrosion resistance. Forging of Incoloy 925 Hex Head Bolts is done at 927 Degree C to 1177 Degree C (1700 Degree F to 2150 Degree F). Incoloy 925 Acorn Nuts is useful for fasteners, marine, pump shafting and high – strength piping systems. Solution treatment in Incoloy 925 Square Bolts is carried out in the range 1800 Degree F / 1900 Degree F (980 Degree C / 1040 Degree C) for 30 minutes to 4 hours – depending upon section size – followed by water quenching.
Cemented carbides in Incoloy 925 Dome Nuts generally produce the highest cutting rates and are recommended for most turning operations involving uninterrupted cuts. Incoloy 925 U-Bolts is age – harden able alloy of nickel – chromium – iron, which is further an alloy of high resistance to corrosion and high mechanical strength. Incoloy 925 Coupling Nuts is a nickel – iron – chromium alloy which is age harden able, with elements of titanium, copper, aluminum and molybdenum.
The chemical composition of Incoloy 925 Eye Bolts is designed to provide a combination of high strength and excellent corrosion resistance. Incoloy 925 Panel Nuts has outstanding resistance to both reducing and oxidizing acids, to stress – corrosion cracking, and to constrained attack such as pitting and crevice corrosion.
