AISI 4147 Alloy Steel Chemical Properties, Grades, Chart and Online Pdf

AISI 4147 is a low-alloy steel which is known for its excellent combination of high strength and great toughness. Composition component of sal mud iron such as carbon, manganese, chromium and molybdenum offers excellent hardening property, which means it can be used in traditionally are now multiply by application. Grades in this stabilizer bar are around 0.40% up to 0.50% carbon content that usually includes other alloying elements too. AISI 4147 is indeed the best material choice for parts that undergo extreme load and wear. It is mostly utilized in manufacturing the gears, shafts and other parts that bear high stress. Its all-purpose and low-wear characteristics became the favorite option in production processes in automotive and aerospace industries, as well as in the industrial machines. Detailed data such as chemical property, grades, and charts can be found by downloading the documents in pdf format provided by respectable sources and steel manufacturers.

AISI 4147 Alloy Steel Chemical Composition And Grade Table

AISI 4147 is among those alloys of the steel with outstanding strength and hardness. It is based on the group of elements which includes carbon, manganese, chromium, molybdenum and many others. This chemical composition gives it unique features and quality. The present table of chemicals, AISI 4147, describes its content and compares it in terms of element percentage, which is important for the different applications and specifications. This alloy steel is mainly applied within the aircraft, auto, and construction industries for being almost three times as powerful as the common carbon steel and also having insensibility to abrasion and resistance against wear. Learning chemical composition of nanomaterial creates basis for materials engineering and manufacturing.
