東邦焼鈍 List of Products and Services

We will introduce the finishing characteristics of various atmosphere gases, as well as the types of processed steel or their applications. The atmosphere gases "DX, N2" enable temporary rust prevention through scale thickness adjustment and are effective in reducing pre-treatments such as pickling. They are suitable for steel materials with a carbon content of 15 or less, which will undergo various plating in subsequent processes. Additionally, "RX, DX, N2" can prevent surface decarburization and carburization, allowing for softening treatment without changing the properties of the material. "Atmospheric annealing" is suitable for those requiring rust prevention on the surface after softening treatment. 【Features】 ■ DX, N2 - Enables temporary rust prevention through scale thickness adjustment - Effective in reducing pre-treatments such as pickling ■ RX, DX, N2 - Prevents surface decarburization and carburization - Allows for softening treatment without changing the properties of the material ■ Atmospheric annealing - Suitable for those requiring rust prevention on the surface after softening treatment *We do not actually perform the treatments; we welcome inquiries from companies needing support regarding annealing. *For more details, please feel free to contact us.

In general, iron products go through various processes from the material stage when they come from major steel companies to become final products, during which they change shape in various ways. In these processes, internal strain can occur in the iron, and if the processing is too strong, it can crack. The heat treatment that removes such strain and prevents processing cracks is called "annealing." There are different types of annealing depending on the application, such as "full annealing," "spheroidizing annealing," and "stress relief annealing." The heat treatment called quenching, which is performed close to the final product state, aims to harden the iron, while the annealing performed at the material stage aims to soften the iron. Additionally, using our facilities, we can also perform "normalizing" operations. **Main Types of Annealing** - Full Annealing - Spheroidizing Annealing - Stress Relief Annealing *Please note that we do not actually perform the treatments; we welcome inquiries from companies that need support regarding annealing.* *For more details, please feel free to contact us.*
