The ability of a ferrous alloy to form martensite when quenched from a temperature above the upper critical temperature.
A term applied to steels to describe the relative ease with which martensite can be formed in the steel. The lower the cooling rate at which a fully martensitic microstructure can be formed in the steel when it is cooled from austenitic condition the higher is the hardenability. Hardenability is commonly assessed by the Jominy end quench test.
The fundamental characteristic of a steel which determines the ease of preventing the transformation of austenite to anything else but martensite during the quench.
(Of Steel)The ability of a steel to harden when cooled from its hardening temperature, as measured below the surface.
a measure of the depth to which a specific ferrous alloy may be hardened by the formation of martensite upon quenching from a temperature above the upper critical temperature.
The steel's ability to be hardened.
The property that determines the depth and distribution of hardness when steel is heated to a given temperature and then quenched (more precisely it may be defined as an inverse measure of the severity of cooling conditions necessary to produce on continuous cooling a martensitic structure in a previously austenitized steel i.e. to avoid transformations in the pearlitic and bainitic ranges). The lower the cooling rate to avoid these transformations, the greater the hardenability. The critical cooling rate is largely a function of the composition of the steel. In general the higher the carbon content, the greater the hardenability, whilst alloying elements such as nickel, chromium, manganese and molybdenum increase the depth of hardening for a given ruling section.
the ability of a steel to achieve a desired hardness under defined conditions of heating and cooling.
In a ferrous alloy, the property that determines the depth and distribution of hardness induced by quenching.
The hardenability of a metal alloy is its capability to be hardened by heat treatment. It should not be confused with hardness, which is a measure of the material's resistance to indentation or scratching. It is an important property for welding, since it is inversely proportional to weldability, that is, the ease of welding a material.
