Description

34CrNiMo6 grade steel is a general purpose steel used for a wide range of engineering parts.

It is capable of being heat treated to produce a wide range of tensile strengths combined with good ductility and resistance to shock.

34CrNiMo6 has good hardenability, enabling it to be used for medium tensile strengths in fairly large sections, and possesses good resistance to wear. At low temperatures good impact values can also be obtained.

Bars are often supplied in the hardened and tempered condition with a tensile strength exceeding 1000 N/mm2 (depending on section size). Material is readily machinable so that the components can be put into service without the cost of further treatment.

Bars can also be supplied in the softened state which require hardening and tempering but give increased machinability.

Nickel-chromium-molybdenum steels benefit from a combination of alloying elements. Nickel imparts toughness; chromium depth of hardness; molybdenum inhibits temper brittleness and each element tends to reduce grain size.
