- 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.
- Pre heat carefully, then raise temperature to 850-1200°C for forging. Do not forge below 850°C. After forging cool slowly in still air.
- Heat the EN19T slowly to 680-700°C. Cool in air.
- 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.
- 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, quenching medium and work piece transfer facilities.
- Please consult your heat treatment provider for full guidance on heat treatment of EN19T alloy steel.
