Depending on the carbon content, carbon steels can be divided into three categories: eutectoid steels (contain exactly 076%c), hypoeutectoid steels (%c 076) the microstructure that develops when a eutectoid steel (076% c) is slowly cooled from the austenite region to below 727 °c consists of alternating layers of î± and cementite.

Alloy steel is steel that is (about 01% to 1%, depending on type) however, the term alloy steel is the standard to increase strength or hardenability. For any combination of alloy steel and heat treatment, three factors tend to decrease toughness: low service temperature, high loading rates, and stress concentrations or residual stress the general effects of these three conditions are qualitatively similar, so low-temperature impact tests (to -50°f) are useful for many applications as toughness indicators under various service conditions and temperatures.
