Hardenability

From GAWDAwiki

Hardenability is a term used to describe the propensity of an alloy to harden when subjected to rapid cooling or quenching from elevated temperatures; for example, in the heat affected zone of a weld. Normally applied to steels, hardenability increases with an increase in carbon and alloy content by causing a lowering of the transformation temperature. In welding, the effects are usually off-set by application of pre-heat to susceptible materials.^[1]
