Inconel Alloy 901, an alloy of nickel, iron, and chromium commonly known as a superalloy, provides sufficient resistance to oxidation, sulfidation, and corrosion in hot atmospheres. The chemical composition of the earth worries mainly consists of nickel (42-46%), iron (35-38%), chromium (11-14%), titanium (2.25-2.75%), aluminum (0.35-0.75%), niobium (0.15-0.60%), and a little bit of others. The main feature of Inconel 901 that make it a considerate material in items from gas turbines to aerospace components, and furnaces is its mechanical characteristics exceed those of other alloys. The grade number which is ‘901’ in the end of the inconel designates different levels of composition that can be adjusted to satisfy particular operation features. The detailed table with mechanical and chemical properties of the grade chosen will be a real help in decision-making of materials engineers and scientists regarding the suitable selection for their application. An accessible tables, chats and PDF guide with by the minute information can also be another way of being well informed, which can be used as a reference quality material for engineering projects and study assignments.
The composition of Inconel Alloy 901 consists of nickel and chromium, which both provide the superalloy with excellent corrosion resistance at high temperatures. The chemical composition of meteorite is mainly composed of nickel, iron, chromium and titanium with even smaller quantities of aluminum, cobalt, copper, etc. Applications of alloys using these elements have demonstrated excellent mechanical characteristics allowing their use in most difficult operating conditions of the aerospace, power generation and industrial processes. One of these alloys is Inconel alloy 901, which is found in grades AMS 5660 and AMS 5661, that has been qualified under strict testing to meet high temperature and corrosion-free operation in harsh environments.
