Nickle Alloy Angle Bar Inconel 718 UNS NO7718
Nickle Alloy Angle Bar, or angle iron, is basically manufactured by hot-rolled high strength Nickle Alloy steel. It has L-cross shaped section with two legs - equal or unequal and the angle would be 90 degree. Structural steel angles have lots of dimensions to comply with your uses. In addition, bespoke sizes are available. I
Many Uses:
- Supporting & structural factors - bridges, warehouses, shelves, cable towers, power towers, communication towers, equipment, etc.
- Everyday life uses - bed frames, chairs, benches, fencing posts, frames for supporting air conditioner, coffee tables and so on.
Inconel 718(UNS NO7718) is a GammaPrime strengthened aloy with excelent mechanicalproperties at elevated temperatures, as wel as cryogenidtemperatures. Suitable for temperatures up to around1300 °F. Can be readily worked and age hardened. Excellent strength from -423 °Fto 1300°F(-253 'C to 705C).Age hardenable and may be welded in fully agedcondition, Excellent oxidation resistance up to 1800 °F(980 °C).Typically sold in the solution annealed temperbut can be ordered aged, cold worked, or cold worked &aged. Alloy 718 is a high strength, nickel base, superalloy usedfor cryogenic temperatures up to long term service at1200 °F. This alloy is readily fabricated and may be weldedin either the annealed or precipitation hardened(aged)condition.718 is annealed at 1700-1850 'F and air cooledor faster. lt is aged at 1325 °F for 8 hours, furnace cooledto hold at 1150 'F, for a total aging time of 18 hours, thenair cooled.Alloy 718 wil show a contraction of 0.0008inch/inch after precipitation hardening. Good mechanical properties: tensile,fatigue, and creep-rupture. Excelent welding characteristics and resistant to postweld age cracking. Oxidation resistant throughout its useful temperature range.
Applications:
Uses for this alloy tend to be in the field of gas turbine components and cryogenic storage tanks. Alloy 718 iscommonly used in jet engines, pump bodies and partsrocket motors and thrust reversers, and hot extrusiontooling.Other popular uses are high strength bolting anddown hole shafting.
