Steel products made of Inconel 718

UNS N07718- Inconel 718 ®

The marketing general names of alloy: Inconel 718 ®, Alvac ® 718, Nicrofer ® 5219, Altemp ® 718, Hines ® 718. An alloy on a nickel basis is additionally quenched. It possesses high properties of elongation to break resistance at temperatures not higher than 704 °C. In comparison with Inconel 617, this alloy possesses a perfect weldability by virtue of titanium and aluminium presence. This alloy is used for high-speed details of aeronautic engines (disk, gasket, bandages, tie-down fitting, male screw) that work at high temperature.

Manufacture

Manufacture of semi-fabricates performs in malleablize hardened condition. Inconel mill-products 718 are represented with further types: rod, welded and seamless pipe, wire, plate, sheet, flange, connecting piece and forging. Sheet has a thickness 0,25 — 1,6 mm or made to order thickness to 4 mm. Rod is made in a form of forging with a diameter not more than 230 mm. The bigger sizes can be made to order. A coiled material is made in large-format sizes; its widths constitutes 900−1200 mm and a wideness of plate is up to 100 mm. Seamless tube Inconel 718 can be rolled to a diameter not more than 200 mm. Huge diameters can be made to order in a form of welded tube. All products (with a welding seam) are exposed to a method with tight tolerances of nondestructive control. Practically, tubes can be manufactured of any diameter and an extent of allowance does not depend on a size of order.

Processing

This alloy has a high plasticity and it can satisfactory be taken to molding. But it is disposed to a hammer hardening. That is why it must be cut at small speeds with a special tool. It differs with a perfect weldability by virtue of titanium and aluminium presence. Welding is done without further heat treating or previous heating.

Welding

Type Description
limitedly weldable welding is possible at heating to 100−120°С and further heat treating
hardly weldable in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding, to heat it up to 200−300°C, to do a heat treating (annealing) after welding
weldable
without stint
welding is done without further heat treating or previous heating
