Steel will not be a perfect material for all applications. Its drawbacks might limit its usefulness as outlined below:
Quenching involves heating the steel to create the austenite section then quenching it in drinking water or oil. This quick cooling leads to a hard but brittle martensitic structure.[twelve] The steel is then tempered, and that is only a specialised sort of annealing, to reduce brittleness.
