where their ability to resist abrasion, oxidation and corrosion, makes them ideal for ancillary applications, where they subjected to pressure and heat, such as pumps, piping and separation machinery.

Extreme environments

Their resistance to oxidising chemicals and high-temperature oxidising gases, means that alloys in the INCONEL series - particularly INCONEL® alloy 600, INCONEL® alloy 617, INCONEL® alloy 690 and  INCONEL® alloy 693, are encountered in extreme environments. They are used in the manufacture of drilling equipment, as well as in the construction of downhole shafts.

INCONEL® alloy 600 has the desirable combination of high strength and good workability. Resistant to corrosion by many organic and inorganic compounds, it is virtually immune to chloride-ion stress-corrosion cracking.

Corrosive aqueous environments

INCONEL® alloy 617 offers a combination of metallurgical stability, strength, and oxidation resistance at high temperatures, as well as being resistant to a wide range of corrosive aqueous environments.
Commonly used in mining applications, corrosion resistant INCONEL® alloy 690 has high strength, good metallurgical stability, and favourable fabrication characteristics.

Newcomer, INCONEL® alloy 693 has a high chromium content that gives it excellent resistance to oxidation and sulfidation as well as vastly improved resistance to other forms of high temperature corrosion.

Another super alloy, INCOLOY® alloy 825, is used in shaped screening wires used to size mineral particles. Resistant to reducing and oxidizing acids, INCOLOY alloy 825 also resists stress-corrosion cracking and localised attack, such as pitting and crevice corrosion. It is especially resistant to sulphuric and phosphoric acids, so can be found in oil and gas well piping.
