ISO/TR 15608 Material Group 45 such as alloy 825:
Nickel-iron-chromium alloys (Ni-Fe-Cr) with Ni ≥ 31 %
Nickel-Iron-Chromium alloys composition such as alloy 825
The high nickel content is sufficient for resistance to chloride-ion stress-corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. As an austenitic, nickel-base alloy, the material is ductile over a wide range of temperatures from cryogenic to well in excess 538°C . Fabricability is typical nickel-base alloys, with the material readily formable and weldable by a variety of techniques.
Applications of Nickel-Iron-Chromium alloys such as alloy 825
The main applications are chemical processing, pollution control, oil and gas recovery, acid production, pickling operations also for
- pipes, tubes and fittings in the oil and gas extraction, e. g. in heat exchangers, evaporators, washers, immer- sion pipes in sea water cooled heat exchangers, offshore piping
- Components in sulfuric acid pickling plants like heating coils, vessels, boilers, baskets and chains
- Heat exchangers, evaporators, washers, immersion pipes in phosphoric acid production
- Food industry
Alloy 825: High Corrosion Resistance
Nickel-Iron-Chromium alloys have a high level of corrosion resistance. In both reducing and oxidize environments, the alloy resists general corrosion, pitting, crevice corrosion, intergranular corrosion, and stress-corrosion cracking.
