EN19 / EN19T Steel
EN19 / EN19T steel manufacturers and suppliers,supplied in Round Rods,Square/Flat Bars,Rollers,Shafts,Blocks and forging pieces,produced as forged and rolled.
EN19 steel is a common chromium-molybdenum alloy engineering steel.EN19T is similar to grade BS 708M25 but the carbon content is a little higher,which gives EN19 steel greater strength and heat treatment capabilities than 708A25. At the hardness of HRC18-22,EN19T alloy steel can be machined well. This material also has high hardenability and good toughness.

EN19 alloy steel is a good material for gears, piston pins, crankshafts,and shafts.It is also used in the oil and gas industry,gear, supercharger drive gear, rear axle, the load of connecting rod.Examples of applications for EN19T steel also includes structural tubing,connection rods, stem assemblies, tool holders.
1)Preheat EN19 steel carefully.
2)Raise the forging temperature up to 1150-1200°C.
3)Keep the forging temperature above 850°C.
Hardening&Tempering(quenched and tempered and after stress relieved)
1)Heating EN19T steel uniformly to 850°C;
2)EN19 alloy steel should be quenched in the oil;
3)Heat the material to the temperature 550°C;
4)Soak at this temperature for at least 2 hours;
5)EN19T engineering steel should be cooled in the furnace.
(In case after QT a straightening process is necessary then the products should be tempered and distorsion-poor annealed with at least more than 625°C.)
1)Heating EN19 forged steel thoroughly to 840-860°C;
2)Cool slowly to the temperature 580°;
3)Complete annealing the steel in the air.
