The balance of high Si and low C is characteristic! The composition of Ni, Cr, and precipitation strengthening elements is adjusted according to the application.
Generally, martensite in iron alloys that do not contain carbon is soft and highly ductile, but on the other hand, it has low strength, and since there is almost no carbon present even after tempering, carbide precipitation hardening is not achievable. Instead of carbides, fine precipitate particles of intermetallic compounds are dispersed to enhance strength, as seen in precipitation-hardened stainless steels such as SUS630 and SUS631, as well as ultra-high-strength maraging steels. Among silicoalloy steels, "Silicoalloy A2" and "Silicoalloy XVI" utilize the precipitation hardening mechanism, particularly characterized by the refined matrix structure of "Silicoalloy XVI," which has hard intermetallic compounds precipitating.

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.
