This document includes detailed test data on laser cladding (laser overlay processing) using Silcolloy XVI metal powder, a new laser cladding technology with Silcolloy XVI + WC (tungsten carbide) dispersion, laser heat treatment (local solution heat treatment), seizure tests, pitting resistance tests, and measurements of residual austenite and residual stress. It also provides comparative materials on Silcolloy and various types of stainless steel.

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.

This is an introduction to the hardness reduction test of age-hardened materials after holding at 700°C. The aim is to investigate the hardness reduction in a short-term high-temperature holding environment, assuming processes like brazing. Test specimens that have undergone aging treatment were placed in an electric furnace (atmospheric furnace) held at 700°C, and hardness measurements were conducted after removing them at various set times and allowing them to return to room temperature. Additional aging treatment (460°C for 4 hours in air) was performed on the same specimens, followed by re-measurement. For more details, please download and refer to the catalog. [Test Specimens] - Material: Silico Alloy XVI (round bar) φ28mm × 10mm, cut into 4 pieces - Solution Treatment: 1050°C/WQ - Preliminary Aging: 200°C for 2 hours in air - Age-Hardening Treatment: 460°C for 12 hours in air - Polishing Finish: Polished with #400 waterproof paper (oxide scale removed) *For more details, please refer to the PDF document or feel free to contact us.

To compare practical seizure phenomena, we conducted seizure tests using special nuts. The special nuts are designed to prevent loosening and utilize the internal spring action (SUS301) to strongly compress the threads of the bolt, generating friction torque that prevents free rotation. Typically, they are used with lubricants, but this time we applied them without lubrication to conduct seizure tests and compare various materials. For more details, please download the catalog and take a look. 【Testing Method】 ■ Fasten the special nuts onto bolts of each material (M17×40, pitch 1.0) (Screw in with a wrench and then unscrew) ■ Conduct seizure evaluation * For more details, please refer to the PDF materials or feel free to contact us.

Our company conducted an evaluation of the seizure resistance of bolts and nuts. We performed a comprehensive comparative test using various materials, the presence or absence of surface treatment, the type of surface treatment, and the presence or absence of high-temperature oxidation tests, following the anti-seizure treatment test methods. The test types correspond to the standards of the Japan Water Works Association JWWA G 113 and G 114 for anti-seizure treatment tests. For details such as test results, please download and view the catalog. 【Test Conditions (Partial)】 ■ Tightening Torque: 100 N·m ■ Nut Movement Distance During Tightening: 5–10 mm (Target Value) ■ Number of Tightening Cycles: 5 ■ Test Specimen Size: Hexagonal Bolt and Nut, M16×90 (Partially Threaded) ■ Test Specimen Material: SUS304J3, Silicoloy A2 (OAG), SUH660 (ST) *For more details, please refer to the PDF document or feel free to contact us.

We will introduce the laser heat treatment tests for "Silicoloy." Laser heat treatment technology can minimize thermal effects on the base material compared to high-frequency heat treatment, allowing for localized hardening or softening. By combining the heat treatment characteristics of the precipitation-hardened Silicoloy with laser heat treatment (localized solid solution heat treatment), we aim to establish a new process design. This time, we conducted evaluation tests using the moving solid solution method and high-speed rotating solid solution method. For details of the tests, please download the catalog. 【Moving Solid Solution Test Conditions】 ■ Laser Oscillator: LDF4000 ■ Beam Shape: 11mm x 6mm ■ Absorber: Present ■ Moving Speed: 20cm/min ■ Upper Limit Output: 1000W-1200W *For more details, please refer to the PDF materials or feel free to contact us.

We will introduce the friction and wear characteristics testing of laser cladding (ball-on-disk).

Laser cladding technology can minimize the thermal impact on the base material, allowing for low dilution, low distortion, fine, and thin-layer buildup. By applying the high corrosion resistance, high hardness, wear resistance, and good fluidity of "Silicoloy" to laser cladding, we aim to establish a new process design. This time, we conducted evaluation tests using metal powder of the precipitation-hardened Silicoloy through laser cladding.

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.
