Inconel 693® - alloy 693 circle, wire, pipe

Inconel 693® - alloy 693 circle, wire, pipe

Company Avecglob sells at a reasonable price from manufacturers a circle, wire and pipe, which are made of nickel alloy grade Inconel 693® (Alloy 693). The supplier guarantees the operative delivery of rolled metal to any address specified by the customer.

Composition and application

Nickel alloy Inconel 693® (Alloy 693) with an increased content of chromium provides resistance to high-temperature corrosion mechanisms that are inaccessible to most alloys of a similar purpose. In particular, it can significantly reduce or eliminate the risk of metallic sputtering. As a result,

designers of gas generating equipment select this material in synthesis processes, petrochemical processes and other high-temperature environments.

Inconel ® alloy 693 has better resistance to metal dust formation in chemical and petrochemical processing media than any of the currently existing alloys.

The increased chromium content in the Inconel 693 alloy determines its excellent resistance to oxidation and sulphidation. However, the addition of 3.1% aluminum to the alloy significantly improves the resistance also to other types of high-temperature corrosion.

The alloy is used in petrochemistry in the synthesis of gas production, in energy recovery and biomass heaters, for the manufacture of nozzle burners and high-temperature fuel cell reactors.

The chemical composition of the Inconel 693® alloy (Alloy 693), which meets the technical standards and requirements of the UNS N06693 standard, is given in the table:

Ni + Co Not less than 58.0 %
Cr 27.0 — 31.0 %
Fe 7.0 — 11.0 %
Cu No more 0.50 %
Mn No more 0.50 %
Si No more 0.50 %
C No more 0.05 %
S No more 0.015 %

A circle, wire or pipe, manufactured from nickel alloy Inconel 693® (Alloy 693), is offered by Avec Glob company at economically advantageous prices. The supplier makes timely delivery of products to any point. installed by the client.


Basic physical properties of the alloy:

Density, kg / m 3 — 7770;

Melting point, 0 С — 1317… 1367;

The coefficient of thermal conductivity in the temperature range 20… 100 0 С, W / mgrad — 9,1… 10,7;

Specific heat capacity in the temperature range 20… 100 0 С, J / kggrad — 455… 484;

The coefficient of linear thermal expansion in the temperature range 100… 900 0 С, μm / deg — 13,04… 17,01.

Basic mechanical properties of the alloy:

The limit of temporary resistance, MPa — 880… 930;

Yield strength, MPa — 490… 510;

Relative elongation at tension,% — 42… 45;

Modulus of elasticity, GPa — 197.

Technological features of the alloy: ductility and mechanical machinability — good; High-speed operations, such as grinding, milling or turning, must be carried out using water-based cooling fluids. Welding should be performed in an annealed condition. Typically, the welding processes used are arc welding with a tungsten electrode and gas flame welding.

To buy a pipe, circle, wire from Inconel 693® alloy (Alloy 693) at an affordable price, the company Avecglob offers. The supplier makes immediate delivery of the products to any point agreed by the customer.
