Heat treatment is a process or several processes contained heating and cooling a solid metal or alloy is such way as to obtain desired conditions or properties , or recovery the properties was existed in metal or alloy which exposed to certain operational process . The objective of this study is to investigate effect of heat treatment on mechanical properties of low-chromium alloying steel (1.1%Cr) with (0.4%) carbon and these properties are : tensile strength , hardness , elongation , and reduction in area . The heat treatments included full annealing which consist of heating steel to(870ºC) and cooling in furnace, hardening which done by heating to(870ºC) and quenching in oil , and tempering in (300ºC and 600ºC ) . The mechanical properties was measured before and after heat treatment as illustrated in the diagrams between heat treatment mechanical properties .The important of this research is that it used a material was used only in militarism fields and calculated its properties to compared them with another steels types for using in civil fields .
