Gas carburizing is a surface hardening treatment that produces a hard, wear-resistant layer (case) on the part surface. Case depth can range from as low as 0.010", to as deep as 0.200". Surface hardness can be as high as 62 - 64 HRC.
Gas carburizing is ideal for improving the surface hardness and wear resistance of low carbon mild or low alloy steels (such as 1018, 1026, 8620, 9310). Parts suitable for this type of surface hardening include pins, rings, gears, sprockets, worm gears, arbors, bushings, wear plates, and other components subject to wear.
Available Quench Types: oil, polymer, water, air blast.

Carbonitriding
-
Carbonitriding is a modified form of gas carburizing, suitable for plain, low carbon steels that would not achieve a uniform case hardness in standard gas carburizing.
-
Carbonitriding is ideal for producing a thin, high hardness case that gives the part improved wear resistance, strength, and increased resistance to softening at elevated temperatures.
Process Selection
For both carburizing and carbonitriding, the optimum case depth will depend on the intended service.
Thermex will meet your precise carburizing / carbonitriding specifications, or recommend the optimal process or combination of processes based on the alloy grade and intended use of the part.
Quality Control
Successful carburizing and carbonitriding both demand precise control of the treatment process. Thermex operates under an ISO 9001 Registered Quality Management System.
Process quality control measures include:
-
monitoring and tight control of furnace temperature, time, atmospheric composition and gas circulation. Carbon levels are precisely controlled using automatic control based on oxygen probes.
-
running our own coupons of matching material with all carburizing & carbonitriding loads. Coupons can then be used for metallurgical analysis in Thermex’s in-house laboratory. These random microhardness case depth surveys ensure that customer specifications are being met.
-
temperature uniformity surveys of furnaces. |
