What is AISI 8617?
AISI 8617 is an alloy steel made up of carbon, manganese, phosphorus, sulfur, silicon, molybdenum, and chromium. It has good machinability and formability properties and excellent strength and hardness levels. The material also offers good weldability with filler metals and high-strength gas tungsten arc welding (GTAW).
AISI 8617 Steel Uses
AISI 8617 steel can be used for a variety of applications, including automotive parts such as camshafts, gears, pinions, shafts, and axles; aerospace parts such as fasteners; power generation components such as turbine blades; medical equipment such as implants; or hand tools such as wrenches. It is also commonly used to produce shafts for pumps or valves due to its excellent corrosion resistance properties.
Heat Treatment & Corrosion Resistance
One advantage of using AISI 8617 steel is its ability to be heat treated to obtain higher strength levels while still maintaining good ductility. Heat treatment involves heating the material to a specific temperature before cooling it rapidly in order to achieve the desired result. This process can also improve wear resistance while decreasing the risk of cracking during machining operations. Additionally, AISI 8617 steel has excellent corrosion resistance, which makes it suitable for use in environments where exposure to corrosive materials could be an issue.
Machining & Fabrication
Because of its good machinability properties, AISI 8617 can be easily cut into complex shapes using traditional machining methods such as turning or milling without significant issues like tool chatter or excessive burrs forming on the finished part. The material also has good formability, which allows for bending without breaking or cracking during fabrication operations like welding or punching holes in metal components.
In conclusion, AISI 8617 steel offers a unique combination of strength, hardness, ductility, and corrosion resistance, making it ideal for use in numerous applications across industries like aerospace engineering or power generation engineering where precision metal components are required. Its ability to withstand high temperatures makes it suitable for heat treatment processes which can further enhance its strength levels while maintaining good ductility properties necessary for successful fabrication operations like welding or punching holes in metal pieces without damaging them beyond repair. Finally, its excellent corrosion resistance means that parts created from this material won’t corrode when exposed to harsh environmental conditions, making them ideal for long-term use in corrosive environments like offshore oil rigs or marine vessels. So if you’re looking for an all-purpose alloy steel, then consider choosing AISI 8617!
