1117 Carbon Steel Machining Services
When a part needs deep, uniform case hardening with faster cycle times than 1018 can deliver, 1117 carbon steel machining services are the right call. 1117 is a manganese-enhanced low-carbon steel alloy engineered for the high-volume production of gears, shafts, and other components that get carburized after machining. Tensile strength runs 82,000 to 92,000 PSI; yield strength runs 72,000 to 82,000 PSI.
E.J. Basler runs 1117 carbon steel machined parts on production lines built for 100,000+ piece programs, with the metallurgical experience to set up the part right the first time.
Properties and Benefits of 1117 Low-Carbon Steel
1117's elevated manganese content does two important things: it increases mechanical strength and it improves machinability over standard 1018. The result is a material that runs faster on the machine and case-hardens more uniformly than the more common low-carbon grades.
Benefits of 1117 carbon steel screw machining:
- Uniform, deep case hardening response after carburizing
- Faster cycle times than 1018 carbon steel
- Strong wear resistance after surface hardening
- Higher tensile strength than 1018 in the as-supplied condition
- Consistent metallurgical response across long production runs
- Strong fit for gear and pinion programs
Applications of 1117 Carbon Steel Machined Parts
1117 carbon steel is the go-to alloy for components that combine machining with downstream carburizing. Common applications include:
- Gears
- Camshafts
- Ratchets
- Pinions and pinion shafts
- Worm gears
- Pump shafts and small axles
- Splined shafts
- Cam followers
- Sprockets
- Lever arms
- Linkage pins requiring case hardening
- Light-duty drive shafts

E.J. Basler manufactures 1117 parts using Davenport machining, Hydromat machining, Swiss machining, and screw machining, all scaled for production runs of 100,000+ pieces. Every component ships with the quality, tolerances, and surface finish your gear or shaft program requires.
Frequently Asked Questions
Why specify 1117 instead of 1018?
1117 has higher manganese content, which gives it better machinability and a more uniform case-hardening response than 1018. If a part will be carburized after machining or needs faster cycle times, 1117 is the better fit. If weldability and lower cost are the priorities, 1018 wins.
Can 1117 carbon steel be carburized?
Yes. 1117 is one of the most commonly carburized low-carbon steel alloys. It produces a hard, wear-resistant case over a tough core, which is exactly what gear teeth, cam lobes, and ratchet pawls need.
What tolerances are achievable on 1117 machined parts?
On Davenport, Hydromat, and Swiss platforms, we routinely hold tolerances within ±0.0005 inches. Post-carburizing grinding can hold tighter tolerances on critical features.
Is 1117 a good choice for high-volume gear production?
Yes. The combination of fast cycle times, uniform carburizing response, and predictable mechanical properties makes 1117 a strong fit for gear, pinion, and sprocket programs running 100,000 pieces and up.
Does E.J. Basler handle the carburizing in-house?
Heat treating and carburizing are coordinated through qualified outside processors. We manage the process flow from raw bar through finished, hardened parts so the customer gets a single point of accountability.
