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

A new heat treatment method that contributes to "environmental impact reduction" 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 that allows nitrogen to penetrate and diffuse into steel, followed by quenching from the austenite state, resulting in low distortion and unique properties. This heat treatment method involves the infiltration and solid solution of nitrogen into steel in the austenite region (γ) of the Fe-N2 phase diagram. It is then rapidly cooled 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 due to ammonia quenching - High surface hardness of HMV800 or more even with SPCC materials - 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 Case Studies ◆ How to View: From the YouTube link at the bottom of this page *For detailed information, please refer to the technical materials available for download in the [PDF Download] section below.
