EN19T / EN19 Steel 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. With a combination of good shock resistance and ductility, in recent years EN19 Carbon Steel Round Bars has become an established material in the Oil & Gas sector.
