EN8 carbon steel material  is through- solidifying medium carbon essence that is constantly hired for making axles, shafts, accoutrements , jolts, and superstuds. EN8 can be machined without any trouble.

EN8 can be warmth handled to  provide a  atrocious  bottom hardness and mild put on resistance through way of  honey or induction hardening techniques.

EN8 engineering  metallic, additionally called 080M40, is an  unadulterated medium carbon metallic. 

EN8 carbon metallic is a not unusual medium carbon and medium tensile metal, with improved strength over moderate steel, via-hardening medium carbon steel. EN8 carbon metallic is also with out difficulty machinable in any condition.

EN8 steels are commonly used in the as furnished untreated condition. But EN8 steels may be in addition floor-hardened by means of induction procedures, generating additives with more suited put on resistance. Steel EN8 materials in its warmness treated bureaucracy possesses accurate homogenous metallurgical systems, giving regular machining homes.

Chemical composition of EN8 steel  :

The following desk indicates the chemical composition of EN8 steel:

Element	C carbon	Si silicon	Mn  manganesium	P phosphorus	S sulphur
Content(%)	0.36-0.44	0.10-0.40	0.60-1.00	0.05	0.005

Hardening of EN8 Steel:

This steel bar can be flame or induction hardened to attain a surface hardness of 50-55HRC.

Forms of supply:

We need to deliver EN8 metal in colourful round bar in drawn grew to come back circumstance or spherical heat rolled, hexagon, blockish, metallic  places and plate.

Heat Treatment of EN8 Steel :

EN8 essence is  usually supplied  undressed however also be able of be furnished to reserve in the  regularized or  in the long run  toast treated,

that is right enough for a wide range of  operations. 

Quenching– In  oil painting or water after hotting to this temperature will harden the metal. 

Tempering – Carbon metallic EN8 or 080m40 can be tempered at a warmness of between 550 °C to 660 °C( 1022 °F- 1220 °F), heated for about 1 hour for every inch of consistence, also cool in  oil portray or water. 

Normalizing- EN8 exceptional slight metal takes location at 830- 860 °C( 1526 °F- 1580 °F)  additionally it is cooled in air.

Forging Properties of EN8 carbon Steel :

Preheat the EN8 metallic cautiously, then increase temperature to 1050°C for forging. Do not forge below 850°C. After forging cool en8 metallic slowly, preferably in a furnace.
