Incoloy901 | UNS N90901
Incoloy901 901 offers excellent corrosion resistance properties to the atmosphere. Even though it has a lower scaling resistance compared to other grades like 309 stainless steel but it is much strength to work in harsh environments.
Tuolian Incoloy901
Incoloy901 is a nickel-iron-chromium alloy composed of aluminum and titanium for precipitation hardening. This also contains molybdenum which is for solid solution strengthening. This type of alloy is known for its creep resistance at 600°C and is equivalent to SPS M259, AISI 682, AISI 681, PWA 1003, and PWA 1002.
Incoloy901 grades have excellent forging characteristics which makes them ideal to use in gas turbines and aircraft for shafts, compressor discs, turbine rotors, and more.
Incoloy901 goes through different testing processes for quality assurance including mechanical tests and full chemical analyses. All materials are inspected and PMI tested known as positive materials identifications before processing methods begin.
After that, all finished incoloy901 goes for final inspections such as visual inspections, dimensional checks, and so much more.
We produce this Incoloy901 in an extensive range of sizes, finishes, and forms. Tuolian rest assured to give you the right incoloy901 grades for your desired needs at a reasonable price.
