– Carbon (C): 0.12-0.17%
– Silicon (Si): 0.15-0.35%
– Manganese (Mn): 0.45-0.70%
– Phosphorus (P): max 0.035%
– Sulfur (S): max 0.035%
– Nickel (Ni): 1.30-1.70%
– Chromium (Cr): 0.50-0.80%
– Vanadium (V): 0.10-0.20%
These chemical elements impart various beneficial characteristics to the steel. Carbon provides strength and hardness, while silicon enhances strength and impact resistance. Manganese improves hardenability and tensile strength. Nickel and chromium increase hardenability, strength, and toughness. Vanadium contributes to the hardenability and grain refinement of the steel.
The technical properties of 14NiCr14 steel make it suitable for a wide range of industrial applications. It exhibits high tensile strength, good ductility, and resistance to wear and fatigue. This makes it ideal for manufacturing gears, shafts, crankshafts, and other components subjected to high stress and heavy loads.
Furthermore, 14NiCr14 steel can be easily heat-treated to achieve desired mechanical properties. It can be quenched and tempered to improve hardness and strength, or carburized to increase its surface hardness while maintaining toughness in the core.
Overall, the combination of excellent mechanical properties, good hardenability, and heat-treatability makes 14NiCr14 steel a preferred choice in the manufacturing of industrial machinery.
