シリコロイラボ List of Products and Services

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.

Precipitation-hardened stainless steel undergoes a different heat treatment process than quenched steel, achieving high hardness through relatively low-temperature heat treatment. This results in fewer issues such as thermal distortion, dimensional changes, cracking, and adhesion of oxide scale, making it effective for improving processing processes. In this study, we investigated the dimensional changes due to heat treatment of precipitation-hardened stainless steel and martensitic stainless steel. This document includes information on "dimensional changes in stainless steel due to heat treatment," as well as "surface modification technologies" and "tempering colors (oxide scale) after aging heat treatment."

This product is particularly used for billet top rollers (foot rollers) and has a proven track record. "Silicoroy A2" is an all-round type of stainless steel that contains approximately 3.5% high silicon in its chemical composition. Silicon contributes to properties such as heat resistance, oxidation resistance, hardness, strength, and corrosion resistance. Due to the approximately 3.5% Si content, it is relatively strong against high-temperature oxidation. 【Features】 ■ Heat resistance ■ Corrosion resistance: Relatively high corrosion resistance against water and strongly acidic powders ■ Fracture toughness (heat check resistance): Minimal occurrence of heat cracks during repeated high temperature to rapid cooling, excellent resistance to crack propagation ■ High-temperature corrosion wear resistance: Superior overall performance contributes to the longevity of the rollers *For more details, please refer to the PDF document 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.
