APPLICATION
NC6 is mainly used to produce cutting tools, tapping machines, chisels, drills, files, machine drills, cold stamping dies and die cutting plates. Medium hardness and high hardness steel, with good machinability and wear resistance. It is characterized by low tendency of bending and dimensional change during hardening, and low toughness and tempering resistance.
NC6 STEEL CHARACTERISTICS
NC6 steel, through carefully designed alloy composition and heat treatment process, perfectly balances the three core indicators of strength, toughness, and wear resistance, becoming one of the preferred materials for manufacturing key load-bearing components.
The excellence of NC6 steel lies in its unique alloy composition and microstructure. The addition of chromium significantly improves the hardenability and corrosion resistance of the material, while nickel effectively improves the low-temperature toughness. This alloy combination enables the material to maintain stable mechanical properties even under high loads, making it particularly suitable for manufacturing critical components that can withstand alternating stresses. The uniform grain distribution inside the material further ensures the consistency of performance and avoids early failure caused by local stress concentration.
The outstanding process adaptability of NC6 steel is an important guarantee for its industrial value. By adjusting the heat treatment parameters, the strength toughness matching of the material can be precisely controlled to meet the usage requirements under different working conditions. Excellent machinability supports various forming processes such as forging and stamping, greatly reducing the manufacturing cost of complex parts. Especially its excellent carburizing responsiveness can achieve an ideal combination of high surface hardness and high core toughness.
In the application field, NC6 steel has been widely used in high-end equipment manufacturing industries such as wind power equipment, engineering machinery, and automobile manufacturing. From heavy-duty gears to high-pressure valves, from ship accessories to aerospace fasteners, its reliable performance has won wide recognition from engineers. This multi scenario applicability not only reflects the excellent quality of materials, but also provides a solid material foundation for the lightweight and long-life development of modern industrial equipment.
