Silicoroy: Hardness reduction test after holding at 700°C for heat-treated material with a statute of limitations.
The thermal conductivity of Silicoroy XVI is 11.9 W/mK! It may have an advantage for a short period of time.
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, such as during 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 returning them to room temperature. Additional aging treatment (460°C×4hr/AC) was performed on the same test specimens, followed by re-measurement. For more details, please download and view the catalog. [Test Specimens] - Material: Silicoalloy XVI (round bar) φ28mm×10mm, cut into four pieces - Solution treatment: 1050°C/WQ - Pre-aging: 200°C×2hr/AC - Age-hardening heat treatment: 460°C×12hr/AC - Polishing finish: Polished with waterproof paper #400 (oxide scale removed) *For more details, please refer to the PDF document or feel free to contact us.

Company information
Silicolloy is a revolutionary new material that contains a large amount of silicon (silicon) and was developed using pure domestic technology. Silicolloy is a super alloy that possesses high strength, heat resistance (high-temperature oxidation resistance), corrosion resistance, wear resistance, high hardness, and low dimensional changes during heat treatment, all in one steel. Currently, many engineers (technicians and designers) are advancing its commercialization, contributing to new product development and total cost reduction through increased longevity. There is 'Silicolloy A2', which excels in overall balance as a precipitation-hardened stainless steel, and 'Silicolloy XVI', which has the highest hardness in the world as a precipitation-hardened type. Those who require both corrosion resistance and high hardness should not miss it!
