Quenched and tempered steels offer high yield strengths with good toughness and are used for structural parts in mechanical engineering and toolmaking. Nitriding steels are heat-treatable steels with higher contents of Chromium, Molybdenum, Vanadium and also Aluminium and are particularly suitable for low-distortion surface hardening using nitriding processes. This significantly increases wear resistance and fatigue strength.
Quenched and tempered steels are low-alloy steels that achieve high tensile and fatigue strength with good toughness through hardening and tempering.
The different alloy contents of carbon, chromium, manganese, molybdenum and nickel, sometimes also vanadium, are very precisely matched to the respective application and have a particular influence on larger cross-sections. The weldability of these steels is limited.
Quenched and tempered steels are used for dynamically stressed parts in mechanical engineering and toolmaking, e.g. shafts and crankshafts, bolts, screws, axles and structural parts.
Nitriding steels are quenched and tempered steels with higher proportions of Cr, Mo, V and sometimes also Al. These are particularly suitable for low-distortion surface hardening by nitriding, which significantly increases wear resistance and fatigue strength.
Fully-killed medium carbon steel. Suitable for medium stressed parts in machinery and industrial tools. Components of small cross section requiring strength and wear properties better than low carbon unalloyed steel. Heavy forgings in the normalized condition for automotive and general engineering, such as axles, clutch members, shafts, pressed and punched parts, piston rods and gear racks.

The Molybdenum additions prevent the steel from being susceptible to temper brittleness. Surface hardenable.
Read MoreNickel, Chromium, Molybdenum steel for applications requiring high tensile strength and toughness values, particularly in large cross sections in the quenched and tempered condition. The addition of Molybdenum prevents the steel from being susceptible to temper brittleness. Higher tensile and yield strength than 4140.
