Carburizing, Nitriding, and Hardening
Covai Air Products’ Atmosphere Solutions are available for carburizing, neutral hardening, carbonitriding, nitriding, and nitrocarburizing. Nitrogen, methanol, and/or a small amount of enriching gas are blended at the furnace to provide a furnace atmosphere essentially identical in composition to that of endothermic. By varying the amount of enriching gas, the furnace carbon potential can be adjusted to meet your specific atmosphere requirements. The benefit of Covai Air Products’ Atmosphere Solutions is superior atmosphere control for consistent part quality, operational cost savings, significant increases in operational productivity, and ease of operation.
Improved operational efficiency and safety
A control system increases flow with a nitrogen purge during charging, quenching, or furnace malfunction, enhancing operation efficiency and safety
High-pressure gas quenching solutions
Gas supply systems up to 40 bar using nitrogen, argon, or helium are available
Improved quality of carburized, nitrided, or hardened components
Covai Air Products’ Atmosphere Solutions for carburizing, nitriding, and hardening provide an excellent means to improve the quality of metal products
Elimination of endo-generation and its associated maintenance produces the greatest impact on cost reduction
