Inconel X-750 Cold-Drawn Bar

Cold-drawn stock in three cycles with closer diameter control for small turned parts.

Grade: Inconel X-750 UNS N07750 Werkstoff Nr. 2.4669
Three Strengths, One Pass

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

Drawing Adds Strength

Cold work raises the tensile floor of X-750 cold-drawn bar before the age even begins.

Closer Diameter Band

Each cold-drawn bar lot is drawn to the diameter band your part drawing states.

PRODUCT OVERVIEW

About Inconel X-750 Cold-Drawn Bar

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

We supply Inconel X-750 cold-drawn bar to ASTM B637 and AMS 5667 in the Type 1, Type 2 and Type 3 conditions. Consequently, the ordered cycle decides the strength level of the cold-drawn bar, and we record it on the purchase order before production.

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

01

Drawing Lifts Tensile

Specifically, the cold work in drawn bar raises tensile past the hot-finished floor of the same size.

02

Creep Life Above 593 °C

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

03

Less Bar Stock Wasted

Therefore, a closer drawn band leaves less material for the roughing pass to remove.

04

Aging Record Shipped

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

05

Machining in the Aged State

The hardened cold-drawn bar matrix machines with carbide tooling rather than heavy cuts.

06

Drawn Hex and Square

In addition, we draw hexagon and square sections as well as rounds.

07

Coil and Straight Lengths

In fact, we ship cold-drawn bar in coils or in cut straight lengths.

08
WHY CHOOSE US

Why Choose Inconel X-750

Sourcing Inconel X-750 cold-drawn bar depends on stating the drawn band before the stock is produced. Where a Swiss-type lathe runs the bar, the diameter band and the straightness decide the cycle time.

01

Cycle and Band Together

Grade, drawn diameter, band 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 cold-drawn bar heat.

03

Reduction Ratio Recorded

In addition, the drawing route and the reduction ratio travel with the cold-drawn bar.

04

Export Papers in One Set

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

MANUFACTURING PROCESS

Reliable Production For Critical Applications

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

01

Charge Selection

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

02

Melt and Refine

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

03

Remelt for Cleanliness

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

04

Hot Rolling to Rod

Forging and rolling reduce the ingot to rod above the recrystallisation temperature.

05

Pickle and Point

The rod is descaled and pointed before the cold-drawn bar enters the draw bench.

06

Cold Drawing

Successive passes pull the cold-drawn bar down to the ordered diameter through carbide dies.

07

Solution and Aging

The cold-drawn bar then receives the ordered solution treatment, and the Type 1 route adds a hold near 843 °C.

08

Test and Release

Finally, we gauge the cold-drawn bar diameter, tensile and surface before the lot is released.

01

Chemistry on the Heat

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

02

Mechanics After Aging

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

03

Drawn Band Checked

In addition, we gauge cold-drawn bar diameter, ovality and straightness against the agreed band.

04

Furnace Chart Attached

Consequently, every cold-drawn 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 cold-drawn bar, while niobium slows its coarsening.

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

Product Form Typical Supply Range
Cold-drawn bar 3-80 mm diameter to ASTM B637
Cold-drawn hex bar 3-40 mm across flats, drawn to band
Cold-drawn square bar 3-40 mm across flats, drawn to band
Cold-drawn and ground bar 3-60 mm diameter held to a tighter band

Cut lengths of this cold-drawn 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 cold-drawn bar with your order.

Surface Condition Typical Use
Cold drawn Close size control and a brighter surface on this cold-drawn bar.
Peeled A machined skin gives this cold-drawn bar uniform diameter for further turning.
Centerless ground Tight diameter and straightness on this cold-drawn bar used as shafting.

For a different profile, the same grade comes as bright bar, centreless ground rod and polished bar.

FAQ

Frequently Asked Questions

Which standard covers Inconel X-750 Cold-Drawn 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 Cold-Drawn Bar?

Type 2 suits cold-drawn 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 Cold-Drawn Bar can you supply?

Cold-drawn bar runs from 3 to 80 mm diameter to ASTM B637, and drawn hexagon covers 3 to 40 mm across flats.

Does cold drawing change the heat treatment?

No. The drawn stock still needs the ordered solution treatment and age. In addition, the cold work raises the tensile floor before aging starts.

What does the Type 1 cycle add to cold-drawn bar?

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

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

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

What is your MOQ for Inconel X-750 Cold-Drawn Bar?

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

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

We quote cold-drawn bar mainly on FOB terms, and EXW or CIF follow on request.

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

Stock cold-drawn 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 Cold-Drawn Bar?

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