As a leading group in metal heat treatment and metal surface treatment, we are constantly dedicated to research and development in heat treatment and ensuring quality stability.
In our lives, there are numerous items that utilize steel materials. This is because steel materials can extensively change their properties through composition and heat treatment, allowing them to be adapted for many applications. The mission of heat treatment is to create properties suited to each intended use, playing a crucial role in ultimately determining the value of the product. At Marushin Seisakusho, which bears this important role, we aim to maximize the properties of metals and other materials through processing technologies that are the foundation of manufacturing.
