Company information
Tool steel is widely used as molds and tools for processing metal materials such as iron, aluminum, and copper into various product shapes. To enhance the durability of molds and tools, tool steel is required to have heat resistance, wear resistance, and toughness. Additionally, it is necessary for it to possess excellent machinability and minimal dimensional changes during heat treatment. Meeting these demands is the microfine steel, known as high-grade tool steel. Microfine steel is a product born from the comprehensive technology of Japan's High-Frequency Steel Industry, utilizing carefully selected materials and unique refining, forging techniques, hot processing, and heat treatment, and has received high praise from many users.
