Zero CO2 Emissions: New Heat Treatment Method 'Nitriding Quenching' with Minimal Distortion Even for Thin Materials

A new heat treatment method that contributes to "reduced environmental impact" and "low distortion" compared to conventional carburizing quenching! Zero CO2 emissions with ammonia quenching.

Aitec's "Nitriding Hardening" is a surface hardening heat treatment method characterized by low distortion, which involves the infiltration and diffusion of nitrogen into steel and quenching from the austenite state. This heat treatment method allows nitrogen to infiltrate and dissolve in the austenite region (γ) of the Fe-N2 binary phase diagram. It then rapidly cools to produce hard nitrogen martensite. Unlike conventional "carburizing hardening," this process uses ammonia for quenching, resulting in zero CO2 emissions during the treatment process! It can be proposed as a new treatment method that considers environmental impact. **Benefits of Nitriding Hardening** ★ No CO2 emissions from quenching with ammonia - High surface hardness of HMV800 or more even with SPCC material - Lower quenching temperature than carburizing, resulting in low distortion (with a proven example of 50% reduction in distortion) - High resistance to softening - Total cost reduction without distortion correction ~ "Decarbonized Heat Treatment Nitriding Hardening Seminar" Video Now Available for Free! ~ ◆ Theme: Decarbonized Heat Treatment Nitriding Hardening Seminar Exploring the Possibilities from Carburizing to Nitriding ◆ Available Video: Nitriding Hardening Mass Production & Development Cases ◆ How to View: From the YouTube link at the bottom of this page *For more detailed information, please refer to the technical materials available for download in the [PDF Download] section below.
