It is stronger and harder, offering better wear resistance and durability, although it can be more brittle if not properly heat-treated. Conversely, 1055 steel, with its lower carbon content (0.50-0.56%), does not retain its edge as well but provides better toughness and flexibility. This makes 1055 steel less prone to chipping or breaking under impact, suitable for heavy-duty tasks like axes where impact resistance is essential.
1055 carbon steel is typically used in the manufacturing of knives, swords, axes, machetes, hand tools, agricultural equipment, blacksmithing tools like hammers and chisels, and automotive and industrial parts that require high strength and impact resistance. On the other hand, 1060 carbon steel is commonly used for high-performance knives, swords (especially Katanas), springs, robust handheld tools, and specific automotive parts, due to its higher hardness, edge retention, and resistance to wear and tear.
The cost of 1055 steel is lower than that of 1060 steel. This difference in cost is primarily due to the lower carbon content of 1055 steel, which simplifies the production process and reduces material costs. Consequently, while both steels are used in similar applications, 1060 steel’s higher carbon content and enhanced performance attributes, such as greater hardness and edge retention, result in a higher price.
Both 1055 and 1060 carbon steels can be heat treated using similar processes, including quenching and tempering, to achieve desired hardness and toughness levels. Quenching involves heating the steel to a specific temperature (typically 805-845°C) and then rapidly cooling it in oil or water to increase hardness. After quenching, tempering is applied to reduce brittleness by heating the steel to a lower temperature (usually 550-660°C) to relieve internal stresses and balance hardness and toughness.
Additionally, normalizing (heating to 825-865°C and cooling in air) helps achieve a uniform microstructure, while soft annealing (heating to 650-700°C) reduces hardness for easier machining. The higher carbon content in 1060 steel allows it to achieve slightly higher hardness levels compared to 1055 steel, but also makes it more prone to brittleness if not properly tempered. Thus, careful adjustment of the tempering process is essential to optimize the properties of each steel type for their specific applications.
