EN19 also known as 708M40 / 709M40 and AISI 4140 comes treated in the annealed as rolled or can be supplied in the T condition. We offer EN19 is a high quallity alloy steel with good tensile strength. We can supply in diameters, squares, and flats from stock. Cut to length if required.
It is renowned for its wear resistance properties and where high strength properties is required. Suitable for automotive applications such as gears, shafts, spindles, etc. If strength is a primary requirement for you application then EN19 should be considered.
