DIN 1.6582|34CrNiMo6 Alloy Steel
DIN1.6582/34CrNiMo6 steel is a heat treatable, low alloy steel,used for a wide range of engineering parts. It is capable of being heat treated to produce a typical tensile strength of 1000 -1200 N/mm² which combined with good ductility and resistance to shock. It also has good hardenability,enabling it to be used for medium tensile strengths in fairly large sections, and attain good wear resistance,good impact property at low temperatures.this material is readily machinable so that the components can be put into service without the cost of further treatment,and also can be supplied in the annealed condition which require hardening and tempering but give increased machinability.it is often supplied in the hardened and tempered condition with hardness 28-34HRC.
