Notice of the "Decarbonization Heat Treatment Nitriding Quenching Seminar" to be held on November 11 (Thursday) and November 17 (Friday).

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.

We will be exhibiting at "JAPAN SHOP 2026," which will be held at Tokyo Big Sight from March 3 (Tuesday) to March 6 (Friday), 2026.

**Lecture Content** "Characteristics of Soil Engineering and Troublesome Issues Anticipated in Design and Construction" (Scheduled Time: 15:00–16:00, 60 minutes) In our disaster-prone country, soil engineering, particularly embankments, has led to large-scale ground disasters due to earthquakes and heavy rainfall, resulting in significant damage. In this lecture, we will explain why soil engineering is vulnerable to rain and earthquakes from a geotechnical perspective, as well as discuss countermeasures for special soils and soft ground, which are treated as troublesome soils in design and construction. Lecturer: Masahiro Okamoto Consultant, Koyo Daiichi Consultants Co., Ltd. Tokyo Branch

The sales department is the face of the company, as it has the most contact with customers (prospects) and builds up performance. However, even in this era where the utilization of digital and AI is being emphasized, know-how such as successful cases and efficient business practices has become personalized, resulting in many sales departments still facing challenges in improving performance and productivity. Have you ever experienced any of the following concerns regarding your company's sales activities? - You want to strengthen new orders, but you are overwhelmed with existing customers and projects. - Prospect and project information is managed individually by sales representatives, making it difficult to grasp the accurate amount of information and actions for the entire department. - You have introduced SFA tools or MA tools, but they are not being utilized. - You are considering the division of labor in the sales process but are unsure how to proceed with personnel allocation, business design, and the establishment of evaluation systems. In this webinar, we will provide hints for solving these issues and introduce successful cases, particularly focusing on the often-cited challenge of "acquiring new projects."
