Acélöntvény

Acélöntvény is a Hungarian term referring to cast steel. It is a metal alloy produced by melting steel and pouring it into a mold to solidify. The process allows for the creation of complex shapes that might be difficult or impossible to achieve through other metalworking methods like forging or machining. Cast steel typically has a higher carbon content than wrought steel, which influences its properties.

The composition of cast steel can be varied to achieve specific characteristics. Common alloying elements include manganese, silicon, and sometimes chromium and nickel, which can enhance hardness, strength, and corrosion resistance. The manufacturing process involves melting the steel, often in an electric arc furnace or an induction furnace, and then casting it into a mold. After cooling, the cast steel part may undergo further heat treatments, such as annealing or quenching and tempering, to improve its mechanical properties.

Acélöntvény finds application in a wide range of industries. It is used for components requiring high strength, toughness, and wear resistance. Examples include machine parts, engine blocks, railway wheels, heavy machinery frames, pump casings, and structural components in bridges and buildings. The ability to cast intricate designs makes it a cost-effective solution for producing large and complex steel parts. However, cast steel generally has lower tensile strength and ductility compared to forged steel of the same composition.
