Incoloy 825 Round Bar Rod (UNS N08825 / W.Nr. 2.4858)

High-strength corrosion-resistant alloy bar rod for chemical processing and pollution control system

As a professional Incoloy alloy supplier, SEATHER TECHNOLOGY manufactures Incoloy 825 (UNS N08825) round bar and rod with excellent quality and outstanding cost performance.

Incoloy 825 is a widely used nickel-iron-chromium alloy offering good resistance to corrosion, particularly in acidic and chloride-containing environments. Compared with higher-grade nickel alloys such as Inconel 625, Incoloy 825 provides slightly lower strength and corrosion resistance, but at a significantly more economical cost. For applications where its performance fully meets service requirements, Incoloy 825 is a highly cost-effective material choice.

We manufacture Incoloy 825 round bar and rod in accordance with ASTM B425 as standard. Round bars are produced by hot rolling or forging, followed by polishing to ensure accurate dimensions and surface quality. Rods are processed by cold drawing based on round bars to achieve tighter tolerances. If required, we can apply bright annealing to relieve internal stress while maintaining a clean and bright surface finish. All Incoloy 825 round bars and rods are carefully straightened to strict standards to ensure excellent straightness and dimensional consistency.

More Information About Incoloy 825 Round Bar Rod (UNS N08825)

When you choose to buy Incoloy 825 Round Bar Rod (UNS N08825), there have some important points we need to know before we get started.

So enjoy the read…

Pitting resistance equivalency numbers (PREN) for Incoloy 825 Round Bar Rod (UNS N08825)

Incoloy 825 PREN: 31.4

The pitting resistance equivalency number uses the alloy’s chemical makeup to guess its power against pitting corrosion. You check how much chromium, molybdenum, tungsten, and nitrogen are in the alloy. These elements help keep the steel safe. The most used formula is:

PREN = CR% + 3.3 x (MO% + 0.5 x W%) + 16 x N%

How to Purchase Incoloy 825 Round Bar Rod (UNS N08825)
