Heavy Sections Covered

We forge X-750 forged bar from 150 to 500 mm diameter for shafts, discs and rings.

Worked Structure

Each forged bar lot carries a forged and recrystallised structure with its furnace record attached.

PRODUCT OVERVIEW

About Inconel X-750 Forged Bar

Inconel X-750 forged bar ships in UNS N07750, a precipitation-hardening nickel-chromium-iron alloy. Titanium and aluminium build the gamma-prime precipitate inside this forged stock. Niobium then slows its coarsening, so the forged bar holds strength to 704 °C.

We supply Inconel X-750 forged bar to ASTM B637 in the Type 1, Type 2 and Type 3 conditions. Consequently, the ordered cycle decides the strength level of the forged bar, and we record it on the purchase order before production.

Meanwhile, the Inconel X-750 Bar and Rod hub also lists this forged bar beside the other forms. The European call-out NiCr15Fe7TiAl maps to the same UNS N07750 material as this forged bar.

Inconel X-750

Three Cycles on One Bar

Type 2, Type 3 and Type 1 deliver 1170, 1103 and 965 MPa minimum tensile for Inconel X-750 forged bar in that order.

01

Beyond the Bar Range

Specifically, open-die forging covers the forged bar sections that a rolling mill cannot reach.

02

Creep Life Above 593 °C

Moreover, the stabilised Type 1 route guards the creep strength of forged bar where the part runs hot for years.

03

Sonic and Dimensional Testing

In addition, ultrasonic and dimensional checks travel with the forged bar before release.

04

Aging Record Shipped

Each forged bar lot travels with the furnace chart for its own solution treatment and age.

05

Machining in the Aged State

The hardened forged bar matrix machines with carbide tooling rather than heavy cuts.

06

Forged Grain Flow

Open-die working aligns the grain of the forged bar with the load path of the part.

07

Ring and Disc Blanks

We forge X-750 discs and ring blanks from the same forged bar stock.

08
WHY CHOOSE US

Why Choose Inconel X-750

Sourcing Inconel X-750 forged bar depends on fixing the cycle and the forging route before the ingot is cut. Where the disc sees service above 593 °C, the stabilised route protects creep life.

01

Cycle Fixed at Order

Grade, forged diameter and cycle enter the purchase order, because one X-750 forged bar reaches three strength levels.

02

Certificate Names the Treatment

Consequently, each certificate records the solution and aging that the mill applied to that forged bar heat.

03

Forging Route Agreed

In addition, we agree the reduction ratio and the forging temperature range before the forged bar is worked.

04

Export Papers in One Set

Quotations for Inconel X-750 forged bar include the packing list, mill certificate and export documents.

MANUFACTURING PROCESS

Reliable Production For Critical Applications

One melt feeds every forged bar section, and the ordered cycle then sets the final properties. Because titanium and aluminium oxidise easily, melting control for X-750 forged bar matters as much as the press schedule.

01

Charge Selection

Weighed nickel, chromium, iron, titanium and aluminium enter the melt that will become this forged bar order.

02

Melt and Refine

Vacuum induction melting holds titanium and aluminium inside a narrow window on every forged bar heat.

03

Remelt for Cleanliness

Consumable electrode or vacuum arc remelting follows, and the certificate records the route taken for the forged bar.

04

Ingot Preparation

The forged bar ingot is cropped and dressed so that no pipe or segregation enters the forging.

05

Open-Die Forging

A press works the ingot through the agreed reduction ratio, above the recrystallisation temperature.

06

Solution Treatment

The forged bar holds at 982, 1093 or 1149 °C, as the ordered Type requires.

07

Stabilising and Aging

Consequently, the Type 1 route adds a hold near 843 °C, and every forged bar then ages near 704 °C.

08

Test and Release

Finally, we check the forged bar dimensions, soundness and mechanical values before the certificate is issued.

QUALITY ASSURANCE

Strict Quality Control From Production To Delivery

Chemistry and heat treatment decide these forged bar properties together, so our laboratory checks both. Therefore, the certificate reports the cycle that produced the forged bar values.

01

Chemistry on the Heat

The laboratory reads titanium, aluminium and niobium in the forged bar heat, then records each figure against the ASTM table.

02

Mechanics After Aging

Specifically, tensile and yield values for this forged bar come from aged stock rather than solution-treated material.

03

Soundness Testing

In addition, ultrasonic inspection looks for internal defects in the forged bar before release.

04

Furnace Chart Attached

Consequently, every forged bar certificate carries the solution and aging record for the same heat.

TECHNICAL INFORMATION

Technical Specifications

Detailed technical information including chemical composition, mechanical properties, standards and available dimensions.

Chemical Composition

The limits come from ASTM B637, which shares one composition table with the AMS documents for UNS N07750. Titanium and aluminium set the gamma-prime volume in this forged bar, while niobium slows its coarsening.

Iron balances the matrix, and the nickel plus cobalt floor keeps this forged bar austenitic. The full composition table on the Inconel X-750 material page lists every element against its ASTM limit.

Mechanical Properties

The three bar rows reproduce ASTM B637 Table 3 for UNS N07750. Section size matters for Type 2, because heavy bar relaxes to a lower elongation floor. Every value below is a minimum unless the row states a range.

Product Form Condition Tensile Strength, min. Yield Strength (0.2%), min. Elongation, min. Hardness
Bar and rod, ASTM B637 Type 2 Solution treated at 982 °C, aged >=170 ksi (1170 MPa) >=115 ksi (790 MPa) 18% 302-363 HB
Bar and rod, ASTM B637 Type 3 Solution treated at 1093 °C, aged >=160 ksi (1103 MPa) >=100 ksi (689 MPa) 20% 267-363 HB
Bar and rod, ASTM B637 Type 1 Solution treated at 1149 °C, stabilised, aged >=140 ksi (965 MPa) >=90 ksi (620 MPa) 8% 262 HB min.

Type 2 holds over sections up to 63.5 mm, and heavier bar relaxes to 15% elongation and 15% reduction of area. Type 1 trades tensile strength for creep life above 593 °C, which explains its lower elongation floor. Hardness ranges are informative only.

Physical Properties

Design work leans on the published figures for this grade, and density sits at 8.28 g/cm³. Moreover, the magnetic behaviour of this forged bar changes with the heat treatment applied, so the Curie temperature follows the cycle.

The physical properties table on the Inconel X-750 material page carries the remaining values, including the modulus and the thermal expansion.

Heat Treatment

Inconel X-750 is precipitation hardened, so the cycle rather than a simple anneal sets its final strength. We supply the stock in the condition below that your duty needs.

Condition Typical Treatment
Type 2 (single age) Solution treated at 982 °C, then aged near 704 °C
Type 3 (single age) Solution treated at 1093 °C, then aged near 704 °C
Type 1 (stabilised) Solution treated at 1149 °C, stabilised near 843 °C, then aged
Solution treated only Soft stock for buyers who machine and age afterwards

Standards

ASTM B637 is the principal UNS N07750 bar specification, and the AMS 5667 group covers the same forms by melting route. The three designations below settle most enquiries.

Standard Product or Application
ASTM B637 / ASME SB637 Bars, forgings, and forging stock for moderate or high temperature service
AMS 5667 Bars, forgings, and rings, equalized and precipitation hardenable
UNS N07750 - W.Nr. 2.4669 - NiCr15Fe7TiAl Material designations

The full standards list on the Inconel X-750 material page adds the AMS 5668 group, the NACE sour service qualification and the Chinese and Japanese designations.

Pyromet X750, Nickelvac X750, Nicrofer 7016 TiNb, and Inconel are trademarks of their respective owners. We quote those names for reference only, and our deliveries follow the ASTM and AMS documents listed above.

The standard text from ASTM International settles any acceptance question.

Dimensions

Because ASTM B637 prints its own scope, the forged bar ranges below follow that text rather than one house rule. For that reason, state the forged bar diameter, the weight and the ordered length on the enquiry.

Product Form Typical Supply Range
Forged bar 150-500 mm diameter to ASTM B637
Heavy forged bar Sections above 300 mm produced to drawing
Forging stock Billet 150-500 mm diameter for buyer forging
Open-die section Cornered and round sections above the bar range

Cut lengths of this forged bar run from 1 m up to 6 m as standard, and the AMS bar documents cap their scope at 254 mm. Therefore, heavier sections ship as forged product against the same standard.

Surface Finishes

Finish follows the operation that comes next rather than a catalogue default. Moreover, we agree the surface of this forged bar with your order.

Surface Condition Typical Use
Hot-worked As-rolled or as-forged surface on this forged bar where machining follows.
Solution treated and pickled Standard delivery for this forged bar in high-temperature service.
Peeled A machined skin gives this forged bar uniform diameter for further turning.

The same heat also reaches the shop floor as black bar, rings and round bar for other machining routes.

FAQ

Frequently Asked Questions

Which standard covers Inconel X-750 Forged Bar?

ASTM B637 governs the bar, forging and ring forms of UNS N07750. In addition, the AMS 5667 group covers the same forms by melting route and solution treatment.

Which heat treatment should I order for Inconel X-750 Forged Bar?

Type 2 suits forged bar below about 593 °C, because it carries the highest tensile floor at 1170 MPa. Above that temperature, the stabilised Type 1 cycle is the better choice.

What sizes of Inconel X-750 Forged Bar can you supply?

Forged bar runs from 150 to 500 mm diameter to ASTM B637, and heavier sections are forged to your drawing.

Why choose a forged bar rather than a rolled bar?

Open-die forging works the full section of a heavy part. As a result, the forged bar carries a sounder core than a rolled bar of the same size.

What does the Type 1 cycle add to forged bar?

It adds a stabilising hold near 843 °C after the solution treatment of the forged bar. Consequently, the Type 1 route protects creep life above 593 °C at some cost in tensile strength.

Can you supply Inconel X-750 Forged Bar in the unaged condition?

Yes. The AMS bar documents cover solution-treated and equalized conditions for buyers who machine the forged bar parts first and age them afterwards.

What is your MOQ for Inconel X-750 Forged Bar?

A single piece or one coil covers most stock sizes of forged bar, so a short cut is enough for a trial.

What are your trade terms for Inconel X-750 Forged Bar?

We quote forged bar mainly on FOB terms, and EXW or CIF follow on request.

What is the lead time for Inconel X-750 Forged Bar?

Stock forged bar ships in 7 to 15 days, and made-to-order material runs about 25 days.

Do you provide EN 10204 3.1 or 3.2 certificates for Inconel X-750 Forged Bar?

Yes. Every heat ships with an EN 10204 3.1 certificate, and we arrange 3.2 endorsement on request.
