Nickel Alloy Products Guide

Nickel Alloy Buying Guide: Monel 400, Inconel 600/625, Hastelloy C276, Incoloy 800/825 — Plate, Tube, Rod, Wire

When titanium's corrosion envelope is exceeded—by high temperatures, strong reducing acids, or extreme concentrations—nickel alloys take over. This guide covers the most-requested nickel alloy grades, their service envelopes, and how to source plate, tube, rod and wire from one stock-holding supplier.

Grade Selection by Service Environment

Grade Family Service Environment Key Properties
Ni200 / N6 Pure nickel Caustic soda, food processing Excellent ductility, good thermal conductivity
Ni201 Low-carbon pure nickel High-temp caustic service Lower carbon for high-temperature stability
Monel 400 Ni-Cu alloy Seawater, hydrofluoric acid, alkaline solutions Excellent seawater corrosion resistance
Inconel 600 Ni-Cr alloy High temp oxidation, carburizing Good strength to 1093°C
Inconel 625 Ni-Cr-Mo alloy Seawater, acid, high strength High strength + excellent corrosion resistance
Incoloy 800/825 Ni-Fe-Cr alloy Sulfuric acid, phosphoric acid, high temp Good resistance to sensitization
Hastelloy C276 Ni-Mo-Cr alloy Strong oxidizers, wet chlorine, bleach Outstanding in aggressive chemical service
Hastelloy C22 Ni-Cr-Mo-W alloy Broad chemical resistance Improved versatility over C276

Product Forms and Size Range

  • Plate: 0.5–50 mm thickness, width up to 2000 mm
  • Tube: OD 6–114 mm, wall 0.5–10 mm
  • Rod: 6–200 mm diameter
  • Wire: 0.8–8 mm diameter

Stock: ~30 tons across all grades and forms.

Standards

  • ASTM B162 — nickel plate, sheet, strip
  • ASTM B161 / B163 — Nickel and nickel alloy seamless pipe and tube
  • ASTM B160 — nickel rod and bar
  • ASTM B164 — Nickel alloy rod, bar and wire
  • ASME SB series equivalents

Mixed Titanium + Nickel Projects

Because we stock both titanium and nickel alloys, a project that requires Gr2 titanium tube for the condenser and Hastelloy C276 plate for the reactor shell ships on one set of documents, one packing list, one shipment.

How to Quote

Tell us:grade × form × size × quantity × service medium

Example:Hastelloy C276 plate, 10 mm × 1500 × 3000 mm, 2 pcs, for chlorine dioxide service

We recommend the right grade if you provide the medium, temperature and pressure.
