5. Applications
 EN19T was originally introduced for the use in the machine tool and motor
industries for gears, pinions, shafts, spindles and the like. Later its applications
became much more extended and it is now widely used in areas such as the oil and
gas industries. EN19T is suitable for applications such as gears, bolts, studs and a
wide variety of applications where a good quality high tensile steel grade is suited

6.  Forging
 Pre heat carefully, then raise temperature to 850-1200°C for forging. Do not forge
850°C. After forging cool slowly in still air.
 Annealing
 Heat the EN19T slowly to 680-700°C. Cool in air.
 Hardening
 This steel grade is commonly supplied ready heat treated. If further heat treatment is
required annealed EN19 should be heated slowly to 860-890°C and after adequate
soaking at this temperature quench in oil. Temper as soon as tools reach room
temperature.

7.  Tempering
 Heat carefully to a suitable temperature selected by reference to a tempering chart or
table. Soak at the temperature for 2 hours per 25mm of ruling section, then allow to
in air. Tempering between 250-375°C is not advised as tempering within this range will
reduce the impact value.
 Heat Treatment
 Heat treatment temperatures, including rate of heating, cooling and soaking times will
vary due to factors such as the shape and size of each steel component. Other
considerations during the heat treatment process include the type of furnace,
medium and work piece transfer facilities. Please consult your heat treatment provider
for full guidance on heat treatment of EN19T alloy steel.
