EN24 is an alloy engineering steel commonly associated with high-strength components such as shafts, gears, axles, studs, bolts, and heavy-duty machine parts.
EN24 is commonly described in supplier datasheets as a nickel-chromium-molybdenum alloy engineering steel used where strength, toughness, hardenability, and durability are required. Final suitability depends on the applicable standard, supply condition, heat treatment, section size, mechanical requirements, and buyer specification.
