AISI 3120 Nickel Chromium Steel Chemical Composition Properties, Grade, Table and Document

AISI 3120 is a nickel-chromium steel of low alloy content. It is particularly known for its high strength and excellent corrosion resistance. Its chemical pattern generally consists of 17-23% carbon, 66-80% iron, 2.5-3.5% manganese, 1-1.5% nickel, 1.5-2.5% chromium and small proportions of other elements including silicon and sulfur. This product is created out of a superior kind of mechanics which makes it eligible for use in several sectors such as aircraft and automobile. AISI 3120 is used in gear and shaft manufacture as well as components such as these must withstand high mechanical stress and abrasive wear. Tables and documents, in-depth, containing all grade specifications and properties, provide real and reliable guidance for engineering and manufacturing industries through material selection and optimal performance of applications in the production process.

AISI 3120 Alloy Steel Chemical Composition And Grade Table
