AISI 4023 Molybdenum Alloy Steel Chemical Composition, Grade, Chart and Pdf
AISI 4023 is a low alloy steel with outstanding specific strength, ample impact toughness, and considerable hardenability. Generally its chemical composition is profound; it includes carbon, manganese, phosphorus, sulfur, silicon, chromium, and sometimes nickel and copper. However, the remarkable properties are resulted from it. Such grade of steel is frequently used in different fields that have necessity to hold high level of tension as fasteners, shafts and gears. These applications require high durability and wear resistance. Having molybdenum added to it increases the element of hardenability as well as its corrosion resitance, so it becomes applicable to tough conditions. The engineers and manufactures have been displaying their tables, charts and PDFs, where detailed information is available on its construction, mechanical properties, and heat treatments to perform well in different industrial environments is shown.
AISI 4023 Alloy Steel Chemical Composition And Grade Table
AISI 4023 is a kind of alloy steel that is characterized by a relatively low carbon content and the high wear resistance, which is widely employed in applications requiring high tensile strength and wear resistance. This compound would have a chemical structure which could include carbon, manganese, chromium, molybdenum and very small amounts of elements. With an optimal blend of ingredients, it reveals an impeccable hardenability and would make it appropriate for various industrial uses involving gears, axles and forgings. This alloy is held by AISI 4023 and is referred to as medium carbon low alloy steel, commonly undergoing heat treatment to acquire the desired mechanical properties.
