GH4169 Round Bar UNS N07718/Inconel 718 High Temperature Alloy Round Rod Black and Bright Surface

Inconel® 718 is a nickel-chromium, precipitation hardening alloy that can maintain good ductility and high strength up to 1300°F. Inconel 718 has relatively good formability, weldability and excellent cryogenic properties compared to other PH nickel alloys. In addition, this alloy can be readily welded w/out hardening or cracking. Inconel 718 is non-magnetic and has good oxidation and corrosion resistance in aerospace applications.

Michlin offers Inconel 718 per AMS 5662 (capable of) 5663 in round bar. In addition, 718 is offered in plate, sheet, pipe, tube, flat bar and coil. Call today for any Inconel material needs.

APPLICATIONS

Honeycombs, bellows, seal rings

DESCRIPTION

lnconel® 718 is a nickel-chromium alloy being precipitation hardenable and having high creep-rupture strength at high temperatures to about 1300 °F (700 °C). The poor age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling. This alloy has excellent weldability compared to the nickel-base super alloys hardened by Aluminum and Titanium.

TEMPERED

lnconel® 718 can be cold rolled to various tempers. Contact Ulbrich Technical Service for additional information.

HEAT TREAT CAPABILITIES

Two heat treatments are generally utilized for lnconel® 718: Solution anneal at 1700 - 1850 ° F followed by rapid cooling, usually in water, plus precipitation hardening at 1325 ° F for 8 hours, furnace cool to 1150 ° F, hold at 1150 ° F for a total aging time of 18 hours, followed by air cooling. Solution anneal at 1900 - 1950 ° F followed by rapid cooling, usually in water, plus precipitation hardening at 1400 ° F for 10 hours, furnace cool to 1200 ° F, hold at 1200 ° F for a total aging time of 20 hours, followed by air cooling.

* Contact Ulbrich Technical Service for additional information.

ADDITIONAL PROPERTIES

CORROSION RESISTANCE

Refer to NACE (National Associate of Corrosion Engineers) for recommendations.

FINISHES

#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process. #2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D. #BA- Bright annealed cold rolled and bright annealed
#CBA- Course bright annealed cold rolled matte finish and bright anneal
#2 - Cold Rolled #2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished - Various grit finish for specific polish finished requirements.
* Not all finishes are available in all alloys - Contact Ulbrich Sales for more information.

WIRE FINISHES

XC - Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease - Ultra bright finish (for decorative applications) Soap - Soap coating on tempered wire to act as lubricant. * Contact Wire Sales for custom wire finishes.

HEAT TREATMENT
