EN19 / 42CRM04
EN19 / 42CrMo4 Grade Steel Plates
EN19, Engineering Steel is a high quality alloy steel with tensile strength. With a combination of good ductility and shock resistance, EN19 is suitable for applications with very high loading such as engine gear boxes. Popular in the automotive sector it is possible to machine the material extremely accurately, in recent years EN19 has become an established material in the Oil & Gas sector. The material lends itself well to any application where strength is a primary consideration.

Hardening
The steel used for plate’s fabrication is supplied readily by heat treatment. If in case more heat treatment is needed EN19 must be heated slowly at temperature 860 Deg C to 890 Deg C. After that adequate soaking is done at this temperature it is quenched in the oil and tempered soon as reached to the tool temperature.
Annealing
EN19T is slowly heated to a temperature ranging 680 Deg C to 700 Deg C in air. Tempering- carefully heated to an appropriate temperature and soaked at the temperature for about 2 hours every 25mm of the ruling section and then allowed it to cool into an air. Tempering in between temperature ranging 250 Deg C to 375 Deg C isn’t recommended as tempering at this range might decrease an impact value.
Heat treatment
Heat treating temperature that includes the rate of cooling, heating and soaking time varies because of factors like sizes and shape of every steel component. The other considerations at the time of the heat treatment process include furnace type, quenching medium and transfer facility of the workpiece.
