Using the Charpy impact testing machine! Here are the appearances after testing of "Silicoroy XVI" and "SUS440C".
This document includes various heat treatment conditions for precipitation-hardened systems in Charpy impact tests, as well as a comparison of different types of stainless steel. We present photographs of the appearance after testing, including "Silicoloy XVI" and "SUS420J2." The testing machine used was a Charpy impact testing machine (Shimadzu Corporation 300J testing machine). We encourage you to read it. 【Contents】 ■ Testing equipment ■ Shape of test specimens ■ Shape of test specimens (appearance photos) ■ Test specimens and heat treatment ■ Test results ■ Appearance after testing *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 extended product lifespan. There are '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 definitely take note! In 2025, a new material called 'Axia Zero Series' will be developed. This new material is a precipitation-hardened stainless steel that not only has high corrosion resistance and high hardness but also high strength and high durability. 'Axia Zero3' achieves high hardness of 56-58 HRC, high corrosion resistance equivalent to austenitic types, and high strength in the 2000 MPa range. It features hardness obtained through precipitation hardening treatment at 480°C, which minimizes deformation and dimensional changes due to heat treatment and resolves various issues related to quenching.
