AISI 3320 Nickel Chromium Steel Chemical Composition Properties, Grades, Tables and PDF Online
AISI 3320, also called grade nickel-chromium steel, is distinguished by its extreme strength and corrosion resistance characteristics. Generally it consists of nickel, chromium, carbon, manganese, silicon, sulfur, phosphorus and traces of these other substances. This alloy shows high tensile strength, good toughness, and very high wearing resistance which makes it possible to use it for a wide range of assorted industrial purposes for example gear, shaft, and other heavy-duty machinery constituents. The fundamental physical properties of AISI 3320 are diverse. Those differences give an opportunity to an engineer to choose the most suitable alloy. Technical and specification tables as well as table, chate and PDF documents regarding it composition, mechanical properties, and grades are now online which is an incredible resource for engineers, metallurgists, and research in the field.
AISI 3320 Nickel Chromium Steel Chemical Composition And Grade Table
AISI 3320 is a nickel-chromium type of steel that is widely used for its great strength and outstanding corrosion resistance. The chemical content of such a steel typically falls in the range of 0.17-0.22% carbon, 0.70-0.90% manganese, 0.40-0.70% silicon, 1.65-2.00% nickel and 0.70-0.90% chromium with a small quantity of some elements Among other uses of this alloy are in situations which demand toughness and resistance such as gears, drives, and other load-bearing mechanical components. For this category, the properties will differ i.e the grade of steel and heat treatment will depend on the production method. AISI 3320 meets the grade requirement with respect to quality and standard.
