17NiCrMo6-4, referred to as 18NiCrMo5 or 18NCD5, is a high-strength case-hardening steel. It is a carburized steel with good fatigue strength and excellent wear resistance. It is also sometimes referred to as a ‘fatigue-resistant roller bearing’ grade steel. It is widely used in the manufacture of a variety of components such as gears, shafts, axles and pins.
17NiCrMo6-4 steel’s high strength and wear resistance make it well suited for its use in components that need to withstand high loads and impact. The material’s chemical compositions make it suitable for use in both hot and cold applications. One of the distinguishing features of this grade of steel is its high yield strength combined with excellent machinability. It can be machined without much difficulty and can be hardened to a variety of different levels.
In order to further improve its properties, 17NiCrMo6-4 is usually carburized or combined with alloying elements such as nickel or chromium. This helps to increase its wear resistance, service life and fracture resistance. It is also used extensively in hot and cold work tooling applications for applications ranging from aircraft components to marine and automotive parts.
17NiCrMo6-4 is also used for applications such as furnace rolls, stress bearing parts and pins. Here it is used in its normalized and tempered versions. It is also used in hot and cold heading processes, as it is strong and ductile enough to resist the pressures that are involved in the manufacturing process.
17NiCrMo6-4 has a wide range of uses and applications due to its combination of strength and durability. It can be used in hot and cold formable parts and components, as well as in applications that require wear resistance. Its ability to be hardened and/or tempered results in an enhanced service life, which makes it an attractive option in many manufacturing processes. Finally, its machinability and good fatigue strength makes it a preferred choice for many manufacturers of machine components and fasteners.
