High-performance stainless steel "Silicoroy" localized high hardness technology - Workability
Local high hardness technology using precision high-frequency heat treatment! Only the necessary areas can be hardened!
The precipitation-hardened silicon alloy can achieve localized high hardness depending on the application. When both hardness and toughness are required, localized solution heat treatment can be performed, and aging heat treatment can be implemented to achieve high hardness only in the necessary areas. Unlike high-frequency quenching, the precipitation-hardened silicon alloy does not become highly hardened after high-frequency heat treatment. Since it can be sufficiently processed after high-frequency heat treatment (solution treatment), there is greater design flexibility.

Company information
Silicolloy is a revolutionary new material that contains a large amount of silicon (silicon) and was developed using pure domestic technology. Silicolloy is a super alloy that possesses high strength, heat resistance (high-temperature oxidation resistance), corrosion resistance, wear resistance, high hardness, and low dimensional changes during heat treatment, all in one steel. Currently, many engineers (technicians and designers) are advancing its commercialization, contributing to new product development and total cost reduction through extended product lifespan. There are 'Silicolloy A2', which excels in overall balance as a precipitation-hardened stainless steel, and 'Silicolloy XVI', which has the highest hardness in the world as a precipitation-hardened type. Those who require both corrosion resistance and high hardness should definitely take note! In 2025, a new material called 'Axia Zero Series' will be developed. This new material is a precipitation-hardened stainless steel that not only has high corrosion resistance and high hardness but also high strength and high durability. 'Axia Zero3' achieves high hardness of 56-58 HRC, high corrosion resistance equivalent to austenitic types, and high strength in the 2000 MPa range. It features hardness obtained through precipitation hardening treatment at 480°C, which minimizes deformation and dimensional changes due to heat treatment and resolves various issues related to quenching.
