PRODUCT OVERVIEW
About Inconel X-750 Flat Bar
Inconel X-750 flat bar ships in UNS N07750, a precipitation-hardening nickel-chromium-iron alloy. Titanium and aluminium build the gamma-prime precipitate inside this rectangular stock. Niobium then slows its coarsening, so the flat bar holds strength to 704 °C.
We supply Inconel X-750 flat bar to ASTM B637 in the Type 1, Type 2 and Type 3 conditions. Consequently, the ordered cycle decides the strength level of the flat bar, and we record it on the purchase order before production.
Meanwhile, the Inconel X-750 Bar and Rod hub also lists this flat bar beside the other forms. The European call-out NiCr15Fe7TiAl maps to the same UNS N07750 material as this flat bar.
PRODUCT FEATURES
Key Features of Inconel X-750 Flat Bar
Inconel X-750 flat bar is supplied in UNS N07750, the precipitation-hardening nickel-chromium-iron alloy strengthened by gamma prime. Titanium, aluminium and niobium build the precipitate that holds strength to 704 °C. Southerly Alloy supplies and exports X-750 flat bar to ASTM B637 in the Type 1, Type 2 and Type 3 conditions, with EN 10204 3.1 paperwork on every heat.
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 flat bar in that order.
01
Width Without Welding
Specifically, a single flat bar spans the full width of most base plates and rails.
02
Creep Life Above 593 °C
Moreover, the stabilised Type 1 route guards the creep strength of flat bar where the plate runs hot for years.
03
No Molybdenum Listed
Titanium and aluminium carry the strengthening, so the certificate for this flat bar shows no molybdenum.
04
Aging Record Shipped
Each flat bar lot travels with the furnace chart for its own solution treatment and age.
05
Machining in the Aged State
The hardened flat bar matrix machines with carbide tooling rather than heavy cuts.
06
Thickness Held to Drawing
We hold the flat bar thickness and width against the tolerance on your drawing.
07
Heavy Sections Forged
In fact, X-750 rectangles outside the bar scope ship as forged product under the same standard.
08
WHY CHOOSE US
Why Choose Inconel X-750
Sourcing Inconel X-750 flat bar depends on fixing the cycle before anyone cuts the plate. Where the rail sees service above 593 °C, the stabilised route protects creep life.
01
Cycle Fixed at Order
Grade, thickness and cycle enter the purchase order, because one X-750 flat bar reaches three strength levels.
02
Certificate Names the Treatment
Consequently, each certificate records the solution and aging that the mill applied to that flat bar heat.
03
Stock and Cut Lengths
In addition, one enquiry covers standard flat bar sizes and custom-cut lengths of X-750 stock.
04
Export Papers in One Set
Quotations for Inconel X-750 flat bar include the packing list, mill certificate and export documents.
MANUFACTURING PROCESS
Reliable Production For Critical Applications
One melt feeds every flat bar section, and the ordered cycle then sets the final properties. Because titanium and aluminium oxidise easily, melting control for X-750 flat bar matters as much as the rolling schedule.
01
Charge Selection
Weighed nickel, chromium, iron, titanium and aluminium enter the melt that will become this flat bar order.
02
Melt and Refine
Vacuum induction melting holds titanium and aluminium inside a narrow window on every flat bar heat.
03
Remelt for Cleanliness
Consumable electrode or vacuum arc remelting follows, and the certificate records the route taken for the flat bar.
04
Hot Reduction
Forging and rolling reduce the ingot to the ordered rectangle, above the recrystallisation temperature, before the flat bar is cut.
05
Solution Treatment
The flat bar holds at 982, 1093 or 1149 °C, as the ordered Type requires.
06
Stabilising Step
Consequently, the Type 1 route adds a hold near 843 °C before the age of the flat bar begins.
07
Precipitation Aging
The flat bar charge ages near 704 °C, and the chart records the time at temperature for every lot.
08
Straighten and Test
Finally, we straighten the flat bar, cut it to length and release it against the ordered mechanical values.

01
Chemistry on the Heat
The laboratory reads titanium, aluminium and niobium in the flat bar heat, then records each figure against the ASTM table.
02
Mechanics After Aging
Specifically, tensile and yield values for this flat bar come from aged stock rather than solution-treated material.
03
Section Inspection
In addition, we check flat bar thickness, width, length and straightness against standard and drawing tolerances.
04
Furnace Chart Attached
Consequently, every flat 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 flat bar, while niobium slows its coarsening.
Iron balances the matrix, and the nickel plus cobalt floor keeps this flat 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 flat 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 flat bar ranges below follow that text rather than one house rule. For that reason, state the flat bar thickness, the width and the ordered length on the enquiry.
| Product Form | Typical Supply Range |
|---|---|
| Flat bar | 3-150 mm thick, up to 300 mm wide, to ASTM B637 |
| Hot-rolled flat bar | As-rolled rectangles for parts machined all over |
| Peeled flat bar | Uniform thickness with a machined skin for further milling |
| Ground flat bar | Tight thickness control for fixture plates and rails |
Cut lengths of this flat 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 flat bar with your order.
| Surface Condition | Typical Use |
|---|---|
| Hot-worked | As-rolled or as-forged surface on this flat bar where machining follows. |
| Cold drawn | Close size control and a brighter surface on this flat bar. |
| Peeled | A machined skin gives this flat bar uniform diameter for further turning. |
Buyers who machine a different profile order the same grade as square bar, black bar and forged bar.

FAQ
Frequently Asked Questions
Which standard covers Inconel X-750 Flat 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 Flat Bar?
Type 2 suits flat 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 Flat Bar can you supply?
Flat bar runs from 3 to 150 mm thick and up to 300 mm wide to ASTM B637, and cut lengths follow your plate drawing.
Can flat bar be supplied machined on four sides?
Yes. We mill X-750 flat bar on all four sides to a square and parallel condition, then age the finished plate.
What does the Type 1 cycle add to flat bar?
It adds a stabilising hold near 843 °C after the solution treatment of the flat bar. Consequently, the Type 1 route protects creep life above 593 °C at some cost in tensile strength.
Can you supply Inconel X-750 Flat Bar in the unaged condition?
Yes. The AMS bar documents cover solution-treated and equalized conditions for buyers who machine the flat bar parts first and age them afterwards.
What is your MOQ for Inconel X-750 Flat Bar?
A single piece or one coil covers most stock sizes of flat bar, so a short cut is enough for a trial.
What are your trade terms for Inconel X-750 Flat Bar?
We quote flat bar mainly on FOB terms, and EXW or CIF follow on request.
What is the lead time for Inconel X-750 Flat Bar?
Stock flat 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 Flat Bar?
Yes. Every heat ships with an EN 10204 3.1 certificate, and we arrange 3.2 endorsement on request.
