Three Strengths, One Finish

A single Inconel X-750 bright bar reaches 965, 1103 or 1170 MPa minimum tensile once the mill fixes the cycle.

Scale-Free Delivery

Every bright bar leaves our line turned, peeled or drawn, so no scale reaches your machine.

Tolerance on the Drawing

We hold X-750 bright bar diameter to h9 or h11, whichever your part calls for.

PRODUCT OVERVIEW

About Inconel X-750 Bright Bar

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

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

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

Inconel X-750 Bright 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 bright bar in that order.

01

Tolerance Held to h9

Specifically, bright bar holds a closer diameter band than hot-finished stock of the same size.

02

Creep Life Above 593 °C

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

03

Scale Already Removed

Therefore, bright bar goes straight into the machine without pickling or rough turning.

04

Aging Record Shipped

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

05

Machining in the Aged State

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

06

Straightness Controlled

We check bright bar straightness so the bar feeds a bar feeder without whip.

07

Coil and Straight Lengths

In fact, we ship bright bar in coils or in cut straight lengths.

08
WHY CHOOSE US

Why Choose Inconel X-750

Sourcing Inconel X-750 bright bar depends on agreeing the finish and the cycle together. Where a bar feeder runs the stock, the straightness and the diameter band decide the yield.

01

Cycle and Finish Together

Grade, bright diameter, finish and cycle enter the purchase order at the same time.

02

Certificate Names the Treatment

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

03

Tolerance Agreed Up Front

In addition, we state the bright bar diameter band and the surface condition on the offer.

04

Export Papers in One Set

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

MANUFACTURING PROCESS

Reliable Production For Critical Applications

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

01

Charge Selection

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

02

Melt and Refine

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

03

Remelt for Cleanliness

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

04

Hot Reduction

Forging and rolling reduce the ingot to bright bar stock above the recrystallisation temperature.

05

Cold Finishing

Turning, peeling or drawing then brings the bright bar to its ordered diameter and surface.

06

Solution Treatment

The bright 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 bright bar then ages near 704 °C.

08

Final Inspection

Finally, we gauge the bright bar diameter, straightness and surface before the lot is released.

QUALITY ASSURANCE

Strict Quality Control From Production To Delivery

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

01

Chemistry on the Heat

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

02

Mechanics After Aging

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

03

Diameter and Straightness

In addition, we gauge bright bar diameter, ovality and straightness against the agreed tolerance.

04

Furnace Chart Attached

Consequently, every bright 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 bright bar, while niobium slows its coarsening.

Iron balances the matrix, and the nickel plus cobalt floor keeps this bright 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 bright 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 bright bar ranges below follow that text rather than one house rule. For that reason, state the bright bar diameter, the tolerance and the ordered length on the enquiry.

Product Form Typical Supply Range
Bright bar 3-100 mm diameter, cold finished to ASTM B637
Peeled bright bar 20-300 mm diameter with a machined skin
Ground bright bar 3-100 mm diameter held to h9
Bright bar, close tolerance Tight diameter and straightness by agreement

Cut lengths of this bright 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 bright bar with your order.

Surface Condition Typical Use
Cold drawn Close size control and a brighter surface on this bright bar.
Peeled A machined skin gives this bright bar uniform diameter for further turning.
Bright annealed A scale-free surface on this bright bar for instrument and clean circuits.

Any neighbouring section ships from the same heat, including cold drawn bar, polished bar and centreless ground rod.

FAQ

Frequently Asked Questions

Which standard covers Inconel X-750 Bright 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 Bright Bar?

Type 2 suits bright 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 Bright Bar can you supply?

Bright bar runs from 3 to 100 mm diameter cold finished, while peeled bright bar reaches 300 mm with a machined skin.

Which tolerance can bright bar hold?

Bright bar holds h9 or h11 bands under ISO 286-2 as standard. In addition, we quote tighter bands where the bar feeder needs them.

What does the Type 1 cycle add to bright bar?

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

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

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

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

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

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

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

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

Stock bright 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 Bright Bar?

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