EN24 ALLOY STEEL: EN24 ALLOY STEEL: EN24 is aN excessive strength metallic alloy that is additionally known as 4340. It is furnished, tempered, and hardened. It is popular and extensively used due to its tremendous strength in numerous additives, which includes bolts, gears, and studs. Other grades can be surfacedhardened to create parts with stepped forward water resistance through nitriding or induction. EQUIVALENT GRADES OF EN24: Country

Forging Properties of EN24: Preheat carefully, then raise temperature to 1000-1100°C for forging. Do now not forge the steel beneath 850-1100°C. After forging cool slowly preferably in a furnace. Forms of EN19 Steel Pipes: Outer Diameter(OD)-Upto 550mm Inner Diameter(ID)-upto 400mm Length-Upto 6000mm length Forms of EN24 alloy Flat bar steel: EN24 Flat EN24T flat sections can be produced via go slicing from massive cast machined billet.
Flat bar/Rolled flat bar-thickness upto 50mm width upto 455mm Forged flat bar-thickness upto 305mm and width upto 455mm Forms of EN24 alloy steel Round bar: EN24 Round Bar EN24 is produced in a massive variety of round bar sizes starting at 6.35mm up to about 1 metre in diameter. Rolled round bar – diameter 16mm to 250mm Heavy forged round – diameter 200mm to 450mm Heavy machined round – diameter 260mm to 620mm Forms of En24 alloy steel plates: Width upto 2000mm Length upto 6300mm Thickness upto 120mm EN24 applications: When used for programs in its heat treated circumstance EN24T combines excessive tensile strength with shock resistance. It is simple to work and may be forged or stamped with out trouble. EN24 is machinable inside the annealed circumstance or when hardened and tempered. • Power transmission gears and other gears requiring maximum hardness. • Bolts, screwed components, stub axles, swivel fingers required very tough. • Structural additives with top high tensile wishes. • Cranks, axles, propellor and gearbox shafts requiring good high tensile residences. • Connecting rods, unique cranks and different elements required to be stiff and but preserve a
excessive degree of toughness. • Plastics and rubber moulding industry parts for moulds, hob preserving earrings, stop pins.
