シリコロイラボ Product Lineup

A comprehensive catalog that explains the all-around stainless steel "Silico Alloy," which combines multiple properties in a single steel. We offer several catalogs, including a digest version, a technical catalog, and one for professionals.

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.
