Carbonitriding for Gears, Machined Parts & Stampings at ThermTech
Carbonitriding is a sought-after heat treatment process due to the significant enhancement to wear resistance, surface hardness, and other pivotal properties of steel components subject to this specialized form of heat treatment. At ThermTech, we leverage this process, especially for plain carbon steels, to ensure gears, machined parts, and stampings stand up to rigorous use.
Carbonitriding at ThermTech:
- Ideal for Plain Carbon Steels:
- ThermTech is commonly employed to perform carbonitriding on parts made from plain carbon steels. Given the low hardenability of these steels, they respond best to case depths ranging from 0.005″ to 0.020″.
- Versatile Applications:
- From heavy gauge stampings to low alloy machined components and gearing, our carbonitriding processes caters to a wide range of parts.
- Superior Facilities:
- Our furnaces, which are maintained to be compliant to AMS 2750 standards, allow us optimal process and lot control. Our largest furnace boasts a working dimension of 36” x 54” x 72”, accommodating weights of up to 5000 pounds.
The Carbonitriding Process:
- Procedure: Austenitizing the heat-treat load in a controlled, carbon & nitrogen rich atmosphere based on the desired case depth requirement, followed by an oil quench to harden the developed case.
- Selective Case Hardening: Using carb stop-off paints, selective hardening can be achieved.
- Unique Capabilities: ThermTech can conform to specific carbonitriding requirements that many other heat-treaters find challenging due to our ability to polymer quench post the carbonitriding cycle.
Expert Recommendations from ThermTech:
We frequently advise the carbonitriding process for hardening heavy-gage stampings, low-alloy machined parts, and gears. Typically, case depths are achieved in the .003-.020” range due to the low hardenability of the steels. However, thanks to our advanced capabilities, we can achieve case depths exceeding 0.100” even with the most marginal materials.
ThermTech proudly offers carbonitriding for a wide variety of steel alloys. Among the ones we most frequently treat include:
- Case hardening of 1018
- Case hardening of 1117
- Case hardening of 12L14
- Case Hardening of A-36
Conclusion:
At ThermTech, we employ carbonitriding to guarantee that components such as gears, machined parts, and stampings offer peak performance, durability, and longevity.
