The heating retention period can be individually set, and salt bath quenching prevents quenching distortion and cracking.

Iwata Tool conducts salt bath heat treatment services for both its own products and external products as a tool manufacturer. Utilizing the know-how of high-speed tools, we confidently carry out the treatment. Salt bath heat treatment has many advantages that vacuum heat treatment does not offer. Particularly for tools requiring toughness, such as drills and punches, there is currently nothing superior to salt bath heat treatment. Additionally, because salt bath heat treatment is processed sequentially rather than in batches, appropriate treatment is applied regardless of the size of the lot. As a result, we can flexibly accommodate small lots. Furthermore, the cooling capacity of the salt bath is very rapid, allowing for heat treatment of large items that is impossible with other heat treatment methods. A uniform heating state is achieved, resulting in stable quenching hardness. After heat treatment, all products undergo long hours of washing, pickling, and rust prevention neutralization. Additionally, upon request, we also perform shot blasting with glass beads and apply rust prevention oil. For more details, please contact us or refer to our catalog.

basic information

**Features** - Salt bath heat treatment by tool manufacturers - Salt bath heat treatment has many advantages that vacuum heat treatment does not have - Flexible response even for a wide variety of small lots → Processed sequentially rather than in batches, allowing for appropriate treatment regardless of lot size - The cooling capacity of the salt bath is extremely fast → Enables heat treatment of large items that is impossible with other heat treatment methods → Achieves stable quenching hardness due to uniform heating conditions - Improved work performance through triple tempering → High-speed steel materials undergo three tempering processes to thoroughly eliminate residual austenite → Compared to the typical double tempering, the performance of the workpiece is enhanced due to secondary hardening, improved toughness, and stress relief (SR) - Fast lead time → If items are delivered by the morning of the heat treatment days (Monday, Wednesday, and Friday), they can be shipped or handed over by the afternoon of the following day - Thorough post-treatment → All products undergo long hours of hot washing, acid washing, and rust prevention neutralization treatment → Additionally, shot blasting with glass beads and application of rust prevention oil can be performed upon request For more details, please contact us or refer to the catalog.
