EN24T also known as 817m40. EN24 comes treated in the T condition to 850/1000 N/mm2 we can offer EN24T in plate from 10mm thick up to 300mm, diameters from 10mm up to 950mm, squares from 20mm to 300mm and flats 20 x 10 up to 3000 x 300mm from stock. EN24T is a popular grade of through-hardening alloy steel due to its machinability in the “T” condition. EN24T steel is used in components such as gears, shafts, studs and bolts. EN24T can be further surface-hardened to create components with enhanced wear resistance by induction or nitriding processing.
