Request Availability →Inconel X-750 Wire
Cold-drawn spring wire in No. 1 and spring tempers for coil and disc springs that run hot.
Two Tempers, One Alloy
Inconel X-750 wire ships in No. 1 temper for hot duty and spring temper for highest tensile.
Relaxation Resistance
A coiled X-750 wire spring keeps most of its installed load after long hours at 650 °C.
Coils Gauged Every Pass
We measure X-750 wire diameter on the drawing line, so the coil holds its band end to end.
PRODUCT OVERVIEW
About Inconel X-750 Wire
Inconel X-750 wire ships in UNS N07750, a precipitation-hardening nickel-chromium-iron alloy. Titanium and aluminium build the gamma-prime precipitate inside this drawn wire. Niobium then slows its coarsening, so the wire keeps useful load at 704 °C.
We supply Inconel X-750 wire to AMS 5698 in No. 1 temper and to AMS 5699 in spring temper. Consequently, the ordered temper decides the tensile band of the wire, and we record it on the purchase order before drawing starts.
Meanwhile, the Inconel X-750 Bar and Rod hub also lists this wire beside the other forms. The European call-out NiCr15Fe7TiAl maps to the same UNS N07750 material as this wire.
PRODUCT FEATURES
Key Features of Inconel X-750 Wire
Inconel X-750 wire 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 wire to AMS 5698 and AMS 5699 in the No. 1 and spring tempers, with EN 10204 3.1 paperwork on every heat.
Inconel X-750
No. 1 Temper vs Spring Temper
No. 1 temper wire carries the higher service temperature, and spring temper carries the higher tensile.
01
Load Held at Temperature
Specifically, a spring wound from X-750 wire keeps its installed load through long hot service.
02
Drawing Lifts Tensile
Moreover, successive drawing passes raise the tensile band of the wire above the annealed floor.
03
Diameter Monitored
Therefore, we gauge the wire at every drawing pass so the coil stays inside its band.
04
Aging Record Shipped
Each wire lot travels with the furnace chart for its own age at 732 or 649 °C.
05
Coils and Cut Lengths
In addition, we ship the wire on spools, in coils or as straightened cut lengths.
06
Tangles Kept Out
Each wire coil leaves on a spool with controlled tension.
07
Grain Size Reported
In fact, a grain size reading travels with every spring temper wire lot.
08
WHY CHOOSE US
Why Choose Inconel X-750
Sourcing Inconel X-750 wire depends on matching the temper to the coiling step. Where the spring is formed after delivery, the softer No. 1 temper wire takes the bend without cracking.
01
Temper Fixed at Order
Grade, wire diameter, temper and cycle enter the purchase order at the same time.
02
Certificate Names the Treatment
Consequently, each certificate records the drawing passes and the age applied to that wire heat.
03
Trial Spools Available
In addition, a single wire spool proves the coiling behaviour before a production run.
04
Export Papers in One Set
Quotations for Inconel X-750 wire include the packing list, mill certificate and export documents.
MANUFACTURING PROCESS
Reliable Production For Critical Applications
One melt feeds every wire coil, and the ordered temper then sets the final properties. Because titanium and aluminium oxidise easily, melting control for X-750 wire matters as much as the drawing line.
01
Charge Selection
Weighed nickel, chromium, iron, titanium and aluminium enter the melt that will become this wire order.
02
Melt and Refine
Vacuum induction melting holds titanium and aluminium inside a narrow window on every wire heat.
03
Remelt for Cleanliness
Consumable electrode or vacuum arc remelting follows, and the certificate records the route taken for the wire.
04
Roll to Rod
Forging and rolling reduce the ingot to wire rod above the recrystallisation temperature.
05
Pickle and Coat
The rod is descaled and coated so the wire carries a clean surface into the dies.
06
Multi-Pass Drawing
Successive carbide dies pull the wire down to the ordered diameter, with in-line gauging at every pass.
07
Age the Coil
The wire then ages at 732 °C for No. 1 temper or at 649 °C for spring temper.
08
Spool and Test
Finally, we spool the wire and release it against the ordered tensile and diameter band.

QUALITY ASSURANCE
Strict Quality Control From Production To Delivery
Chemistry and drawing decide these wire properties together, so our laboratory checks both. Therefore, the certificate reports the temper that produced the wire values.
01
Chemistry on the Heat
The laboratory reads titanium, aluminium and niobium in the wire heat, then records each figure against the AMS table.
02
Tensile on the Coil
Specifically, tensile values for this wire come from the finished coil rather than from the rod.
03
Diameter and Ovality
In addition, we gauge wire diameter and ovality at the start, middle and end of every coil.
04
Coil Records Attached
Consequently, every wire certificate carries the drawing 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 wire, while niobium slows its coarsening.
Iron balances the matrix, and the nickel plus cobalt floor keeps this wire austenitic. The full composition table on the Inconel X-750 material page lists every element against its ASTM limit.
Mechanical Properties
The wire rows come from the AMS spring wire documents for UNS N07750. Diameter decides the applicable band, and the temper decides the aging cycle. 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 |
|---|---|---|---|---|---|
| No. 1 temper wire, AMS 5698 | Cold drawn, aged at 732 °C for 16 h | 165-220 ksi (1138-1517 MPa) | - | - | - |
| Spring temper wire, AMS 5699 | Cold drawn, aged at 649 °C for 4 h | 180-250 ksi (1241-1793 MPa) | - | - | - |
| Spring temper wire, long cycle | Solution treated, stabilised, aged | 145-190 ksi (1000-1310 MPa) | - | - | - |
Wire diameters up to 0.64 mm follow their own tensile bands in the AMS documents. The drawn temper lifts tensile past the bar floor, and no further aging applies afterward.
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 wire 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 wire is cold drawn and then aged, so the temper rather than a separate anneal sets its final strength. We supply the wire in the temper below that your spring needs.
| Temper | Typical Treatment |
|---|---|
| No. 1 temper | Cold drawn, then aged at 732 °C for 16 h |
| Spring temper | Cold drawn, then aged at 649 °C for 4 h |
| Long-cycle spring | Solution treated, stabilised, then aged |
| Soft (as-drawn) | Undrawn stock for buyers who age afterwards |
Standards
AMS 5698 and AMS 5699 are the wire documents for UNS N07750, while the bar and forging forms sit on ASTM B637. The three designations below settle most spring enquiries.
| Standard | Product or Application |
|---|---|
| AMS 5698 | Wire, No. 1 temper, precipitation hardenable |
| AMS 5699 | Wire, spring temper, 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 5589 and AMS 5590 wire documents and the remaining bar numbers.
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 AMS 5698 and AMS 5699 print their own scope, the wire ranges below follow those texts rather than one house rule. For that reason, state the wire diameter, the temper and the coil weight on the enquiry.
| Product Form | Typical Supply Range |
|---|---|
| No. 1 temper wire | 0.5-12 mm diameter in coils to AMS 5698 |
| Spring temper wire | 0.5-8 mm diameter in coils to AMS 5699 |
| Wire, straightened | Cut lengths for cold-forming headers |
| Wire, soft | Annealed stock for buyers who coil first and age afterwards |
Coils ship to the weight named on the order, and each AMS wire document settles its own diameter band. Therefore, fix the temper before the mill draws the coil.
Surface Finishes
Finish follows the operation that comes next rather than a catalogue default. Moreover, we agree the surface of this wire with your order.
| Surface Condition | Typical Use |
|---|---|
| Cold drawn | Close size control and a brighter surface on this wire. |
| Bright annealed | A scale-free surface on this wire for instrument and clean circuits. |
| Peeled | A machined skin gives this wire uniform diameter for further turning. |

FAQ
Frequently Asked Questions
Which standard covers Inconel X-750 Wire?
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 Wire?
Type 2 suits wire 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 Wire can you supply?
No. 1 temper wire covers 0.5 to 12 mm diameter, and spring temper wire covers 0.5 to 8 mm diameter in coils.
Which temper should a spring maker order?
Order No. 1 temper when the spring must run above 593 °C. For the highest tensile, order spring temper wire and finish the spring by grinding only.
What does the Type 1 cycle add to wire?
It adds a stabilising hold near 843 °C after the solution treatment of the wire. Consequently, the Type 1 route protects creep life above 593 °C at some cost in tensile strength.
Can you supply Inconel X-750 Wire in the unaged condition?
Yes. The AMS bar documents cover solution-treated and equalized conditions for buyers who machine the wire parts first and age them afterwards.
What is your MOQ for Inconel X-750 Wire?
A single piece or one coil covers most stock sizes of wire, so a short cut is enough for a trial.
What are your trade terms for Inconel X-750 Wire?
We quote wire mainly on FOB terms, and EXW or CIF follow on request.
What is the lead time for Inconel X-750 Wire?
Stock wire 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 Wire?
Yes. Every heat ships with an EN 10204 3.1 certificate, and we arrange 3.2 endorsement on request.
REQUEST FOR QUOTATION
