What is the chemical composition of Inconel 625?

UNS N06625 / W.Nr. 2.4856: nickel balance, 20-23% chromium, 8-10% molybdenum and 3.15-4.15% niobium plus tantalum.

How does 625 get its strength without heat treatment?

The niobium and molybdenum stiffen the solid-solution matrix, giving high strength in the annealed condition.

What are its mechanical properties?

Tensile about 930 MPa (135 ksi), yield about 517 MPa (75 ksi) and 42.5% elongation.

What are typical applications?

Aerospace ducting, chemical processing, marine engineering and nuclear components.

What standards cover 625?

UNS N06625 / W.Nr. 2.4856, with ASTM B446 and AMS 5666 covering bar and shapes.

Is Inconel 625 weldable?

Yes - it is one of the most weldable nickel alloys, with the niobium preventing sensitization.

Round bar, plate, sheet, tube, pipe, wire, forgings and welding filler.

It resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion.

Quick Answer

What are Cast Superalloys alloys?

Cast nickel superalloys are supplied as vacuum master alloy ingots and investment castings for gas turbine blades, nozzle guide vanes and integral wheels. This index lists 1 technical articles covering composition, mechanical properties, temperature limits, corrosion behaviour and welding practice for each grade.

What is Cast Superalloys?

Cast nickel superalloys are supplied as vacuum master alloy ingots and investment castings for gas turbine blades, nozzle guide vanes and integral wheels. Hangbo Alloy Group stocks and supplies these grades in round bar, seamless tube, plate, sheet, precision strip, forging, wire and machined-part forms, with mill test certificates to EN 10204 3.1 / 3.2.

Which Cast Superalloys grades are covered?

Grade	UNS	Type	Summary
Inconel 713C: Investment Casting Superalloy for Gas Turbine Blades & Vanes	UNS N07713	Grade guide	Complete technical guide to Inconel 713C (UNS N07713). Chemical composition, mechanical properties, casting characteristics, microstructure.

Which cast grades do we supply?

Inconel 713C (UNS N07713 / W.Nr 2.4671, AMS 5377) — integral turbine wheels and nozzle guide vanes.
Inconel 713LC (low-carbon variant) — improved ductility, thermal fatigue and weldability.
Inconel 738LC (UNS N07738, AMS 5410) — hot-corrosion-resistant turbine blades and vanes.

Which product forms are available?

Round bars · Seamless tubes · Plates & sheets · Precision strips · Forgings & rings · Welding wire. Not every grade is stocked in every form — cast superalloys, for example, are supplied as master alloy ingots and investment castings rather than wrought bar. Contact us for current stock and size ranges.

Which standards apply?

Supplied to ASTM, ASME, AMS, DIN/W.Nr., EN, GB and GOST specifications. The individual grade articles list the applicable standard numbers for each product form.

Frequently asked questions about Cast Superalloys

What is a cast nickel superalloy?

A cast nickel superalloy is supplied as vacuum master alloy ingot and investment-cast into near-net-shape hot-section components; these grades are not wrought into bar, plate or tube.

What is Inconel 713C used for?

Inconel 713C (UNS N07713, AMS 5377) is used for integral turbine wheels and nozzle guide vanes where high creep strength and castability are required.

How does Inconel 713LC differ from 713C?

713LC is the low-carbon variant (maximum about 0.05% carbon), giving improved ductility, thermal-fatigue resistance and weldability compared with 713C.

What is Inconel 738LC used for?

Inconel 738LC (UNS N07738, AMS 5410) is a high-chromium cast grade designed for hot-corrosion-resistant gas turbine blades and vanes.

Can cast superalloys be welded?

Most cast superalloys have limited weldability and are usually repaired with specialised procedures; 713LC is notably more weldable than 713C.
