CARBONITRIDING PROCESS PDF

Thermex will meet your precise carburizing or carbonitriding specifications, or recommend the optimal process or combination of processes based on the alloy . Also low-pressure carbonitriding (LPCN) is possible. During this process type, the carbon and nitrogen transfer does not normally take place simultaneously. The carbonitriding process, which involves the diffusion of both carbon and nitrogen into the base steel, can be carried out in a salt bath or in a furnace gas.

Carburizing is a surface hardening treatment that produces a hard, wear-resistant layer case on proocess part surface. Case depth can range from as low as 0.

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, 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.

Carburizing & Carbonitriding | Thermex Metal Treating

Liquid nitriding is suitable for a wide variety of carbon steels, low alloy steels, tool steels, carbonitricing irons, and stainless steels. The resulting lustrous black finish is an effective alternative for both chrome and nickel plating.

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.

Thermex will meet your precise carburizing or carbonitriding specifications, or recommend the optimal process or combination of processes based on the alloy grade and intended use of the part.

Process Selection and Quality Control For both carburizing and carbonitriding, the optimum case depth will depend on the intended service. Thermex will meet your precise carburizing and carbonitriding specifications, or recommend the optimal prrocess or combination of processes based on the alloy grade and intended use of the part. Successful carburizing and carbonitriding both demand precise control of the treatment process. Request a Quote Contact Us.

Suitable for plain, low carbon steels Produces a thin, high hardness case Improved wear resistance, and strength Increased resistance to softening at elevated temperatures Process up to: 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 oxygen probes. Test coupons of matching material are run with all carburizing and carbonitriding loads.
