Free Handbook for Engineers and Designers on High-Performance Stainless "Silico Alloy"

Information packed about an all-around material that combines high hardness, high corrosion resistance, heat resistance, and wear resistance! Two documents (for general use and professional use) are available for free.

We are currently offering two detailed documents (one for general use and one for professionals) introducing the special stainless steel "Silicoalloy," which combines high hardness and high corrosion resistance with properties such as high strength, heat resistance, wear resistance, and anti-seizing characteristics. By actively utilizing silicon (Si), which was traditionally considered an impurity, as a substitute for carbon (C), and further precipitating fine intermetallic compounds, a new material has been born that was previously unimaginable. We have prepared a 'Technical Handbook' that clearly explains the properties for beginners, and a 'Technical Handbook Pro' that contains abundant testing data on various properties. Please make use of these as supplementary materials in the research and development of Silicoalloy (such as Silicoalloy XVI, Silicoalloy A2, etc.), stainless steel (SUS630, SUS440C, SUS420J2, etc.), and heat treatment technologies. Examples of material shapes include round bars, forged materials, wire rods, and metal powders (small quantities of various types). We are currently developing a new Silicoalloy-based material (high strength and high durability type at 2000 MPa level), with a planned release in the autumn of 2024. *For more details, please download the PDF or contact us directly.

Precipitation hardening stainless steel "Axia" *has minimal thermal treatment deformation and dimensional changes.

A new material with a high hardness of 56-58 HRC, high corrosion resistance equivalent to austenitic phase, and high strength of 2000 MPa class has been developed: precipitation-hardened stainless steel!

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.
