"Heat treatment" is a method to enhance the quality of materials, similar to shape processing, and refers to the treatment that changes the properties of materials through heating and cooling. It involves heating and cooling metals and other materials to alter their hardness and properties. This includes processes such as "quenching," "high-frequency quenching," "shot peening," and "surface treatment," which are all part of metal heat treatment. 【Metal Heat Treatment (Excerpt)】 ■ What is heat treatment ■ Quenching ■ Tempering ■ Annealing ■ Normalizing *For more details, please refer to the external link page or feel free to contact us.

Ito Heat Treatment Co., Ltd. is one of the few comprehensive heat treatment factories in the Tohoku region, serving approximately 500 clients from six prefectures in Tohoku to the Kanto and Chubu regions. We specialize in "carburizing and quenching," a process that hardens the surface of steel while keeping the interior soft, which is essential for automotive components such as mission shafts and crankshafts due to its excellent wear resistance, fatigue resistance, and strength against impact and vibration. We conduct heat treatment processing across a wide range of fields, including automotive, motorcycles, and construction, and our ability to handle everything from mass-produced automotive parts to various small quantities of molds and tools is one of our strengths. Please trust us with your heat treatment processing needs. 【Business Activities】 ■ Heat treatment processing of metal products (automotive parts, industrial machine parts, electrical equipment, sewing machines, knitting machines, hydraulic machinery, construction machinery, agricultural machinery, office equipment, etc., across various fields of metal parts) ■ Surface treatment processing of metal products (blackening, shot blasting) *For more details, please refer to our catalog or feel free to contact us.
