Kohlenstoffstahl

Through-hardened - also known as quenched and tempered - steels are characterised by exhibiting high tensile strength, good machinability, good ductility, and good wear-resisting properties.

​

The process to create through-hardened steel is relatively straightforward; they are first heated to temperatures in excess of the austenitic phase (815℃) and then quenched in either water or oil to skip pearlite formation and become martensitic. The martensitic phase is responsible for the material's hardness.

​

Through-hardened steels are used in mechanical engineering applications to create crankshafts, con-rods, gears, high-tensile nuts and bolts, pistons, shafts, spindles, axles, and many more. They are usually supplied in bar form to reflect their machinability.
