Compared to carbonization, deformation and dimensional changes are minimal!
- It is possible to achieve a surface hardness of 800 HV or higher even with low carbon steel. - The amount of gas used is about 1/10 of that for gas nitriding. - There is a high resistance to temper softening. - The finish is better compared to carburizing and similar processes. - Corrosion resistance is better than that of carburizing.

Company information
Through the skillful adjustment of heating and cooling, the special processing technology known as "heat treatment" can make metals both soft and hard, allowing for precise control over strength and durability. Tracing its history back, it has been applied in the crafting of Japanese swords by blacksmiths, deeply rooted in our Japanese culture. In modern times, it is widely recognized as a technology closely tied to the development of the economy and industry, ranging from vehicles like automobiles and aircraft to precision machinery. Particularly in fields requiring high precision, such as aviation, it is evaluated as an indispensable and important technology. We, "Tama Metallurgy," have been professionals in heat treatment since our founding in 1951, growing alongside the development of the Japanese economy. Throughout our long history, we have also experienced hardships due to economic downturns and natural disasters, but we take pride in the importance that heat treatment technology brings to society and have continuously refined our "technology, people, and factories." Moving forward, we will continue to create the future while being inspired and resonating with the connections between people, linking technology, culture, and aspirations to the next generation, with "Mission," "Vision," and "Spirit" at our core.
