A medium carbon steel with content of approximately 0.3% - 0.6% carbon is harder and more stable in most applications over a low carbon steel but still ductile to some extent. Lcpw of medium carbon steel is frequently accompanied by other elements such as manganese, phosphorus, sulfur and silicon to improve strength, rigidity and other characteristics. Carbon steel comes into many diameters of medium carbon grades, for examples AISI 1045, AISI 4140, and AISI 4340, each with various compositions and applications. The charts, tables and pdf provide a voluminous information on the dimensional properties, heat treatment, and area of use of various medium carbon steel grades. Medium carbon steel documents as material specifications and standards not only indicate the necessities and the exact attributes which the medium carbon steel material for other industrial uses has to possess, but also, reveal other justifiable details.
Common medium carbon steel is carbon-contented within the range from 0.3% to 0.6%, which is developed with a balance of both hardness and ductility as a principle. The chemical composition of it which is medium carbon steel contains other components helps to make it more strong and sharp. Metal alloying elements may include manganese, silicon, and numerical traces of other elements like sulfur and phosphorus. These further additions of carbon produce results that are contrary to what might be expected in terms of strength, toughness, and the machinability. Reference tables containing data from industry standards or material data sheets help manufacturing in details. These tables provide information which is key in determining desired mechanical properties, in order to achieve perfect results.
