17CrNi6-6 is a low carbon, nickel-chromium steel used for applications requiring higher toughness and strength than 4140. It is a general purpose steel alloy, particularly suited for parts that require strength combined with good toughness and resilience. Because of its lower carbon content, 17CrNi6-6 is also easier to machine than most other metal alloys.
17CrNi6-6 is commonly used for components in various industries including mining, oilfield, automotive, aerospace, and fabrication. The alloy is known for its good hardness, wear resistance, ductility, and toughness. These qualities make it an ideal material for creating parts that need to be lightweight and durable. Due to its corrosion and abrasion resistant properties, the alloy is also used in a variety of applications where exposure to the elements is unavoidable.
The low carbon content of 17CrNi6-6 makes it well suited for forging, as the forging process can further enhance its toughness and strength. When the forging process is complete the alloy is usually heat treated at temperatures of 1500-1650°F. After this process, the steel is both highly malleable and strong.
In terms of machining, 17CrNi6-6 is relatively easy to work with. It can be drilled, milled, bored, tapped, knurled, and threaded without too much difficulty. The alloy is also resistant to stress cracking and cutting, making it an ideal metal for applications that require complex parts with features that need to remain intact. Moreover, the alloy is resistant to galling and seizure, making it an excellent choice for situations requiring repeated assembly and disassembly.
Due to its excellent machinability and corrosion resistance, 17CrNi6-6 is very popular in applications requiring screws, nuts, bolts and pins, as well as casings, shafts and gears. In addition, the alloy can be used for springs and valve stems, due to its toughness and stiffness. In terms of welding, the alloy can be used with most types of welding including shielded metal arc welding, gas metal arc welding, and subtractive welding.
Overall, 17CrNi6-6 is an excellent choice for applications that require components that need to be durable, strong and lightweight. The alloys low carbon content also makes it easy to work with and suitable for complex machining and welding operations. Despite its relatively high cost, 17CrNi6-6 remains a popular choice among fabricators, thanks to its expansive list of desirable qualities.
