Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Inconel Alloy 718 Nuts And Bolts, which should be given uniform reductions to avoid the formation of duplex grain structures. For most applications, these Inconel 718 Hex Head Bolts is specified as: solution annealed and precipitation hardened (precipitation hardening, age hardening, and precipitation heat treatment are synonymous terms). Inconel 718 Hex Head Nuts is typically used for: Jet engine and Gas turbine operations. These Inconel 718 Square Bolts is non – magnetic, which is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition.
Inconel 718 Square Bolts is age harden able and often used in high temperature dynamic applications. These Inconel 718 U-Bolts has excellent creep – rupture strength at temperatures to 1300 Degree F. This treatment gives the highest room temperature tensile and yield strengths in Inconel 718 Lock Nuts as well as producing the highest fatigue strength. These Inconel 718 Eye Bolts can be easily post – hardened by precipitation – hardening heat treatments.
Inconel 718 Eye Nuts is a high strength, corrosion resistant nickel chromium alloy, initially developed for the aerospace industry and still considered the material of choice for the majority of aircraft engine components. These Inconel 718 T-Bolts is a precipitation harden able nickel – based alloy designed to display exceptionally high yield, tensile and creep – rupture properties at temperatures up to 704 Degree C.
