Hazardous agents 2IntroductionIn the fast growing industry, steel remains to increase its uses as a potential structural and functional materials due to its high strength, soft-magnetic properties, wear resistance and good corrosion together with comparatively low material cost. Steel has a carbon content approximately 0.29 and 0.60 %.Steel is well known to balance strength and ductility and has a good resistance to wear. It is applied in large parts, automotive components and forging. Hence it’s not shocking that much of modern research has been focused on the impactscarbon on the mechanical properties of steel. Even though there has been a lot of research which has been carried out to examine the impact of distortion limitssuch as strain, strain rate and temperature on the plastic characteristic of steel there has been very narrow studies on the effects of carbon content on the mechanical properties of steel.in general as the amount of carbon content increases as the hardness of steel increases at the same time elongation decreases[CITATION Jun16 \p 483 \l 2057 ].From the previous researches which have been conducted it has been that carbon content in steel produces a small change in the softening characteristic atthe deformation temperatures which are usually above no recrystallization temperature. With the increase in amount of carbon content in steel the stress ratio parameters such as oeffective are found to be higher as compared to the pure steel without carbon content.

Hazardous agents 3With the carbon content increase in steel, the microstructure is altered into the martensite and the reserved austenite, plus the solid solution solidification of thecarbon element. The main aim of this research is to evaluate and analysis the impacts of carbon content on the Physical properties of steel.The amount of carbon content has a great influence on the physical properties ofsteel such as; steel toughness which is inversely proportional to the amount of carbon content existing in steel. Increasing the carbon content in steel increases the hardenability of steel so as the weld of steel cools it can successfully be quenched, leading to a hard, brittle material in the heat affected areas[CITATION Jos112 \p 876 \l 2057 ]. Increased amount of carbon content reduces malleability andductility in steel.The mechanical strength and hardness of steel increases with the increase in the amount of carbon content present in steel, But the impact toughness decreases as the hardness and strength increases.Common mechanical properties of steel propertiesSteel strengthSteel strength refers to the capacity of steel to endure loads inclining to elongateas conflicting to compressive strength that endures loads inclining to decrease size. In other words tensile strength opposes tension i.e. being pulled apart. While compressive strength of steel opposes compression i.e. being pulled

The strength of steel is measured by the highest amount of stress that it can withstand when being pulled together or stretched before breaking.Steel Ductility Ductility refers to the extent of the degree through a steel can elongate or strain amid the start of yield and ultimate break under tensile loading as shown below.Many designers who uses steel depends on ductility for a number of phases of design such as reorganization of stress at the final limit state, fabrication process,condensed risk of exhaustion and bolt group design[CITATION Mah132 \p 250 \l 2057 ]. The figure below shows the stress strain for steel.Fig 1: stress-strain behavior for steel.
