Silicoroy is a new material that was born from the research of Japanese researchers who, after many years of study, elucidated the mechanism of high-strength high-silicon steel for the first time in the world (Journal of the Japan Iron and Steel Institute, Vol. 28, No. 9 "The Birth of High-Silicon Tough Steel," Professor Emeritus Keiichi Ota of Kansai University). Inheriting the DNA of an indomitable research spirit, the current "precipitation hardened high-silicon Silicoroy" has been developed.

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.

Precipitation hardened stainless steel achieves high hardness through relatively low-temperature heat treatment, resulting in fewer issues such as distortion, cracking, and oxidation scale attachment compared to quenched steel. This contributes to the simplification of the processing process and shorter delivery times. Precipitation hardened silicon alloy features minimal dimensional changes during aging heat treatment and surface modification processes at temperatures below 500°C. Silicon alloy resolves processing process issues. For more details, please download and view the catalog. 【Heat Treatment Features】 ■ Quenched Steel: Quenching and Tempering - Rapid cooling from high temperatures (water cooling or oil cooling) can easily cause distortion and cracking. - Dimensional changes require finishing processes. ■ Precipitation Hardened Aging Heat Treatment / Two-Step Aging Treatment - Air cooling from relatively low temperatures makes distortion and cracking less likely. - Dimensional changes require finishing processes. *For more details, please refer to the PDF document or feel free to contact us.

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. For more details, please download and view the catalog. 【Examples of Localized High Hardness Products】 ■ Special Shafts - Only the tip and sliding parts are hardened to high hardness (HRC50 and above) - The overall structure retains toughness (HRC35) ■ Bridge Support Rollers - Only the surface of the rollers is hardened to high hardness (HRC50 and above) - The overall structure retains toughness (HRC35) *For more details, please refer to the PDF materials or feel free to contact us.

By precipitating hard metal intermetallic compounds through aging treatment, high hardness and wear resistance are improved; however, there was a challenge where the tensile strength and yield strength of our conventional steel (Silico Alloy XVI) decreased. At Silico Alloy Lab, we succeeded in fine and dispersed design of intermetallic compounds through component design! We have developed a new stainless material that adds [high strength × high yield] to [hardness × corrosion resistance]. 【Features of Axia Zero3】 ■ High hardness of 56–58 HRC ■ High corrosion resistance equivalent to austenitic phase ■ Achieves high strength of 2000 MPa class ■ High hardness can be achieved at tempering temperature equivalent (aging treatment at 480°C) ■ Minimal thermal deformation and dimensional changes It is possible to reduce total costs through new product development, problem-solving, and extending lifespan. *For details, please download the PDF or contact us directly.
