PRODUCT OVERVIEW

About Incoloy 825 Forged Bar

Incoloy 825 forged bar arrives in UNS N08825, the titanium-stabilised nickel-iron-chromium grade whose molybdenum and copper additions face reducing and oxidising acids. Seawater, brine and H2S-bearing streams also sit inside the envelope of this Incoloy 825 forged bar.

We supply Incoloy 825 forged bar to ASTM B425 and ASME SB425 in hot-worked, solution-annealed and cold-drawn conditions. Your order for this 825 forged bar carries heat-number records, hardness papers where sour duty calls for them and EN 10204 3.1 paperwork for goods-in checks. Besides, we agree the anneal and finish on the forged bar before we book the heat.

Meanwhile, the chemistry and the sour-service data behind Incoloy 825 forged bar sit on our Incoloy 825 material page for cross-reference.

Incoloy 825 Forged Bar
Incoloy 825

Sulfuric and Phosphoric Acid Resistance

For example, molybdenum and copper in this Incoloy 825 forged bar cover reducing acid streams across a wide band.

01

Chloride SCC Resistance

Specifically, nickel at 38.0–46.0% keeps this Incoloy 825 forged bar austenitic against chloride stress-corrosion cracking.

02

NACE Sour Qualification

Moreover, UNS N08825 sits inside NACE MR0175 / ISO 15156, so this Incoloy 825 forged bar enters H2S duty with a hardness record.

03

Titanium-Stabilised Structure

Besides, titanium ties up carbon in this Incoloy 825 forged bar, so sensitization does not follow welding.

04

Pitting and Crevice Resistance

In turn, molybdenum lifts the localised corrosion resistance of this Incoloy 825 forged bar in seawater.

05

Cold-Work Strength

Drawing adds yield strength above the annealed floor of this Incoloy 825 forged bar where shafts need it.

06

Weldable Without Post-Weld Heat Treatment

Standard arc practice on this Incoloy 825 forged bar clears most fabrications without any furnace pass.

07

Non-Magnetic Behaviour

Finally, this Incoloy 825 forged bar stays non-magnetic below −196 °C for magnetically sensitive assemblies.

08

MANUFACTURING PROCESS

Reliable Production For Critical Applications

Bar production for Incoloy 825 forged bar runs from charge weighing to final packing. Our team logs each stage of this 825 forged bar route against its heat number.

01

Charge Weighing

Charge weighing comes first, and this 825 forged bar starts from electrolytic nickel, chromium, iron, molybdenum and copper.

02

Melting and Refining

First, the charge for this Incoloy 825 forged bar melts and refines under AOD practice that holds carbon low.

03

Titanium Stabilisation

Next, titanium joins the melt of this Incoloy 825 forged bar so carbon stays tied up against intergranular attack.

04

Hot Reduction

Then, forging and rolling reduce the ingot to this Incoloy 825 forged bar section.

05

Solution Annealing

After that, 927–1010 °C annealing and rapid cooling restore the corrosion resistance of this Incoloy 825 forged bar.

06

Pickling and Descale

Subsequently, acid pickling leaves this Incoloy 825 forged bar scale-free for fabrication.

07

Cold Finishing

We then draw, turn or grind this Incoloy 825 forged bar to the ordered size and finish.

08

Testing and Release

Finally, chemistry, hardness and dimensional checks clear this Incoloy 825 forged bar for dispatch.

TECHNICAL INFORMATION

Technical Specifications

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

Chemical Composition

ASTM B425 holds nickel between 38.0% and 46.0% and chromium between 19.5% and 23.5% for this forged bar, with iron at 22.0% minimum. Moreover, molybdenum at 2.5–3.5% and copper at 1.5–3.0% form the acid-resisting pair behind this forged bar, while titanium at 0.6–1.2% stabilises the structure against intergranular attack.

For the complete element-by-element limits, open the composition breakdown held on the Incoloy 825 material page for this forged bar.

Mechanical Properties

The minimum room-temperature values below follow the rod and bar table of ASTM B425 for UNS N08825. Consequently, the ordered condition and hardness basis govern final acceptance of Incoloy 825 forged bar.

Condition and Grade Tensile Strength, min. Yield Strength (0.2%), min. Elongation, min.
Annealed — UNS N08825 ≥85 ksi (586 MPa) ≥35 ksi (241 MPa) 30%
  • ASTM B425 sets one annealed condition for rod and bar, with the yield minimum applying from 2.4 mm diameter upward and hardness at 200 HB maximum. Moreover, strength above the annealed floor comes from cold work only, because UNS N08825 does not respond to aging, so sour-service orders carry a hardness record against the 35 HRC ceiling.

Physical Properties

Published references place this forged bar at a density near 8.14 g/cm³ with a melting range of 1370–1400 °C. Moreover, the Curie temperature sits below −196 °C, so this forged bar stays non-magnetic even in cryogenic seawater service. Besides, the austenitic matrix keeps these values stable across the whole annealed range.

Meanwhile, the physical properties table on the Incoloy 825 material page holds the modulus, the thermal expansion and the remaining design values behind this forged bar.

Heat Treatment

The solution anneal is the specification-defining step for this grade, because rapid cooling after 927–1010 °C restores the corrosion resistance the media demand. In addition, we supply this Incoloy 825 forged bar in whichever condition your duty calls for.

Condition Typical Treatment
Solution Annealed Held at 927–1010 °C (1700–1850 °F), then cooled rapidly to restore full corrosion resistance
Hot-Worked Delivered as-rolled or as-forged, with the solution anneal agreed where the order calls for it
Cold-Drawn Drawn after annealing, with the reduction recorded so the higher yield strength is documented
Sour-Service Release NACE MR0175 orders carry a per-lot hardness record against the 35 HRC ceiling

Standards

Heavy sections of this forged bar are quoted to ASTM B564, published by ASTM International, whose UNS table lists N08825 for forgings including flanges and tubesheets. Moreover, ISO 9725 and DIN 17754 cover the international and European forging routes for this forged bar.
