Conducted salt spray testing in accordance with JIS Z 2371! Published the time-dependent changes of "Silicorol A2/XVI" and others.
This document includes a comparison of various heat treatment conditions for precipitation hardening systems in salt spray tests, as well as the aging changes of various stainless steels and high alloys. The testing equipment used is a composite cycle testing machine (CYP-90D manufactured by Suga Test Instruments Co., Ltd.). Appearance photographs were taken after 0, 5, 24, 48, 72, 96, and 240 hours, and weights were measured before the test and after 240 hours. Please take a moment to read it.

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.
