Round bars · Seamless tubes · Plates & sheets · Precision strips · Forgings & rings · Welding wire. Not every grade is stocked in every form — cast superalloys, for example, are supplied as master alloy ingots and investment castings rather than wrought bar. Contact us for current stock and size ranges.
Supplied to ASTM, ASME, AMS, DIN/W.Nr., EN, GB and GOST specifications. The individual grade articles list the applicable standard numbers for each product form.
Incoloy is a family of iron-nickel-chromium alloys offering high-temperature oxidation and carburization resistance at lower cost than nickel-based grades.
All share UNS N08800/N08810/N08811 roots but differ in carbon content and grain size control: 800H is specified for creep-rupture service and 800HT for the highest allowable design stresses.
Incoloy 825 is the standard choice for sulfuric and phosphoric acid service thanks to its molybdenum and copper additions.
Age-hardenable Incoloy 925 and 945X are used for downhole tubulars and completion equipment in sour (H2S) wells.
Incoloy 890 is designed for high-temperature furnace applications requiring resistance to oxidation and carburization.
